Hi there, this is my first time posting. I have what seems to be a respiratory issue that is affecting a few of my chickens, and I have no idea what it is.
I have 8 hens and one rooster. We have had all of them for years; some for several years, others for just a couple. Everyone has been healthy, happy, and normal for all that time, we've had no major issues.
Almost 2 years ago we purchased two salmon faverolle hens from the same farm. One was 100% normal and healthy, and the other always seemed a little off. Basically from the day we got her she was kind of sneezy. She also acted a little different from the other chickens - she's much mellower and dopier. Her appetite is great, she moves around with the flock, but she's just very submissive and kind of odd. After having her for a month or so, we noticed that in addition to the sneezing, you could also hear a sound when she breathed, like her nose was snotty and congested. Every once in a while her eyes would crust up too, in which case I would put a warm compress on them and they'd open up and be all better.
So 2 years later, she is still with us and has exactly the same symptoms, with no worsening. And up until 3-4 months ago, NONE of our other chickens had any similar symptoms whatsoever, so we assumed she had nothing contagious. It seems odd to me that if she were ill, she would have either died or passed it to our other chickens after all this time.
So about 3 months ago I noticed that her sister started sneezing a bit too, and I could hear that kind of congested sound when she breathed. And our rooster now sounds like he has a frog in his throat every time he tries to crow. He does not have any sneezing or breathing sounds. But his crow has sounded drastically different for a couple of months.
What could be going on? Besides the things I mentioned, there is nothing else wrong. They are all eating, drinking, laying eggs, tearing apart our yard and doing all the normal stuff free range chickens do.
