Respiratory Illness in Your Flock

It all started, really, with the loss of my Poe. She was a black Easter Egger who had my whole heart and changed me as a human. About a month after Poe died, we had our first hawk attack in the whole six years we have been raising chickens. And I came upon it right in the middle of the attack. Then, about a month later, we had another.

We have a large fenced area (about 3/4 of an acre) for our chickens, complete with lots of trees and many places to duck and cover. In all of our years of keeping chickens, we didn’t have a single hawk attack. When we had two back to back, I started to research heavily. I knew confining everyone to the run was the quickest solution. I read that due to lower than normal numbers of birds in our area that year, hawk attacks were on the rise. But after about a month with our flock confined the run, I realized I didn’t want my flock to live like this. They became stressed and started to exhibit some health issues related to the stress.

I set them free in their 3/4 acre again and decided the risk was worth their happiness– their joy in getting to scratch in the leaves, tromp in the garden for the gleaning, and dust bathe wherever they felt like digging a good hole.

But I had read in some folklore (and while I am an academic and science lover in my mind, I am a folklorist at heart) that black chickens, which look like crows, can help keep hawks away.

It made sense in my heart-broken desperation, of course. With Poe, we had no hawk attacks. Without Poe, hawk attacks.

So I went online and found a local chicken person with black Easter Eggers listed for sale. I was a little worried that the hens, though beautiful, seemed lethargic. We kept them in quarantine for a few days. I was mainly worried about mites. I saw no signs of anything and put them with the flock. I knew I was breaking the rules of quarantine for new birds, but I had done it once before and been lucky.

This time, I would not be so lucky. Desperation and sadness will often lead to bad decisions. This would be no different.

Within a few days, everyone in the flock was acting kind of strange. That’s the only way I can describe it. I remember closing them up one night and realizing they didn’t talk back to me when I told them goodnight. I was scared about what might be going on. Within a week, my first hens were coming down with respiratory issues, and these issues were pretty epic. If I thought the hawk attacks had been my worst nightmare as a chicken owner, I think the realization that my entire flock had been exposed to a serious respiratory issue ran a close second. It was devastating, and it was my fault.

I am terrible at making a long story short, but I need to. I want to help inform others about what I went through and what worked as treatment—and what didn’t work.

I contacted my vet, and we were not able to test for Coryza on a live chicken, but my flock experienced almost all of the symptoms. Because we are not sure if we had Coryza, we have decided to play it safe and keep our flock closed for the rest of ever.

The main symptoms were rales, runny nose, sneezing, and swelling around the eyes and face on some birds. Some also experienced gunky eyes. The only symptom of Coryza we did not experience was the smelly, runny poop. However, I have read that respiratory illnesses can be pretty severe and still not be Coryza, so there is a chance we just had a really bad respiratory illness. Still, I proceeded as if I was treating Coryza.

The rales were the worst, I think. We started out isolating birds who showed signs in our garage, and the rales were so loud some nights I could hear them in the house. It was like some kind of Edgar Allan Poe story where I was being constantly reminded of my sin of bringing in the sick birds, who just so happened to be black and looked like little ravens. You can’t make this stuff up.

I spent months treating what would eventually turn out to be every single member of our flock. Morning and night, I would do rounds of treatments on my sickest patients. Some were highly cooperative; some were not. Of course, they were grumpy at being so sick. I was bitten and scratched, and, of course, I deserved it all, I thought. I work full time and also homeschool my son, so being a nurse to 30 chickens took a toll for sure. I felt so worn.

In the end, I was treating someone from the end of October to the end of January. Below, you will find a list of symptoms and treatments I used. I am just completely honest here about what worked and didn’t work for me.

Others may have different experiences, of course, but I wanted to share what I did, as we did not lose a single hen. I read everywhere that the best thing to do is to cull. I am so glad I didn’t.


Rales (see video below)

Runny nose


Gurgled breathing

Swollen face and eyes (sometimes really swollen)

Gunky eyes

This is what rales sound like. It’s heartbreaking.


TreatmentHow AppliedEffect
Vet RxWarmed and applied to nostrils and around the head. The instructions say you can administer it orally, but I chose not to, as I was putting other things in their little beaks. The instructions also say to put some at the wing, where the chickens tuck their heads, and I did this, only I didn’t keep it to the wing. I noticed where each individual chicken preferred to tuck in and then applied the Vet Rx in that spot. The purpose of this is so the chicken can breathe in the vapors. It’s kind of like an herbal Vicks.This had little effect that I could really notice—but some. I think it may be helpful with much milder symptoms, but I also think it maybe took the edge off when things were at their worst.
Oregano Oil/Olive OilI dosed chickens with 1 ml of olive oil before I got the oregano oil. I used a syringe and put the 1 ml of the olive oil down their throats. When the oregano oil arrived, I used it in their water. You do have to dilute oregano oil quite a bit because it is strong. For preventative, I use one drop per gallon. When I was giving it to the hens with the bad rales, I used two drops per gallon. Both of these seemed to do some good relieving some of the rales—at least taking the edge off. I think the oregano oil worked a little better, but both helped.

It is important to note that the oregano oil, diluted to one drop per gallon, also helps with the long term immune building you will have to do.
OreganoI added dry oregano to food and to nesting areas several times throughout the winter.It is difficult for me to say if this helped, in the immediate, but after two years, I can now say that it helps with long-term immune-system building for sure!
Grapefruit Seed ExtractI added 30 drops per gallon of water every day when I changed the water.The idea with this is that it supposed to help the immune system, kind of like apple cider vinegar. I couldn’t tell much from this, but my chickens did recover. It definitely didn’t hurt and could have helped.
Colloidal SilverI gave sick chickens 1 ml of this in the morning, and when things were at their worst, I tried to do the 1 ml in the morning and at night.This helped more than anything I used, outside of the antibiotics. I found out about it a few weeks in, so I didn’t have it right away. I found it to be amazing at reducing the head swelling and just shortening symptoms overall. I had one hen come down with a very swollen face. I gave her a dose of Colloidal Silver, and by that evening, the swelling was almost completely gone. It is supposed to be an immune system booster, and it worked better than any natural treatment I have ever seen. I will never be without it again.

I now use it, along with the oregano oil, as an immune booster in their water. We have a five gallon bucket for water, and I add one tablespoon.

I use this, alternating with oregano oil, as the long-term preventative.
AntibioticsI took one hen to the vet for help and to get a prescription for antibiotics. Everything I read said to use Tylan 50 for this kind of issue, but it is no longer available over the counter. The vet actually prescribed a different all-around antibiotic. I used the antibiotics on three of our oldest hens who had the worst symptoms and both of our roosters. This worked, of course. One of my favorite hen’s eyes were so infected I thought we were going to lose her, but after two days on the antibiotics, the swelling was down and she was on the mend. The issue with this is that my vet visit cost more than $200. Also, as I heard and then learned from this experience, the illness can and did come back anyway, just as with other treatments. Everyone who was treated with antibiotics did relapse. But I am glad I had the antibiotics for my worst cases.
Clean Dry CoopAs soon as we found out what we were dealing with, my husband and I stripped down the coop and cleaned it from top to bottom. My husband vacuumed any dust in the nooks and crannies and in the rafters.This worked, but it’s critical to keep it up, like forever. You have to make sure you have really good ventilation, and you just have to keep the coop really clean. In the late winter, after everyone seemed to be healed up and over the respiratory illness, we had some really damp cold weather, like swampy and miserable. The coop got a little damp because we forgot to open up the front vents, and two chickens started sneezing and gurgling again. Keeping the coop super clean and dry for the rest of ever seems to be critical.

I think the moral to this story is to not give up hope, even if your entire flock gets really sick. I have some really old hens who took a long time to get well. Both of my hens who had the antibiotics were older and relapsed pretty hard. They were both sick for nearly three months! But you would never know it now. They are happy and healthy now.

Preventative Measures

I have also learned that I now have to live my life as a chicken keeper in preventative mode. I have to constantly work to limit stress, keep the coop super clean and dry, and use natural supplements to build my flocks immune systems.

For preventative, I use the grapefruit seed extracts in the dosage listed above, oregano oil, and I use small amounts of the colloidal silver. At least every other day or so, I add 1 tablespoon of the colloidal silver to their five gallon water bucket. I have also just started using oregano oil in the water to try something different than the colloidal silver, and it worked as well. I also continue to periodically add dry oregano to food, especially in winter. Winters are the toughest times for relapsing, though I should note that I have never had more than some mild relapses.

As a testament to the success of these treatments, last summer, we let several of our broody hens raise babies. I was very worried about what might happen. Of course, these babies could never leave our property, as our flock is closed forever, but the babies all did very well. When the weather turned cold, the young chickens did get some very mild symptoms with a little sneezing and coughing, but the symptoms passed rather quickly and with no treatment beyond my preventative measures that have now become my habits. Their immunity is being built, and that’s really what beating this is all about, I think.

*Please note I was not paid to promote any of these treatments. I simply research treatments others had tried and tried them myself. My opinions are based only on my experiences treating my chickens. If you have any questions, you can post them below, and I will do my best to answer them. Please just keep in mind that I cannot diagnose chicken illnesses and believe that no one really can very well over the internet.
