Here’s an update, the female chick seems completely healthy. But the male is still breathing weird. Pretty much non stop. He is not hot, and there is adequate ventilation. Most of the time he sounds like a ceiling fan that’s wiggling because it’s loose. Squeak. Squeak. Squeak...
But he’s eating and drinking. Doesn’t appear to be very weak. Other than his breathing difficulty, he seems normal. I do have rooster booster on order. Think it could be something genetic? I’ve looked up all the chicken illnesses I could find, but this one doesn’t seem contagious since the other one is fine.
