I have 15 chickens. 5 that are 8 1/2 months old, 4 that are about 2 months old, and 6 who are probably 3 or 4 months. The 10 younger ones all came together almost 2 months ago. Of the 10, 4 are bantam orpingtons. 3 black and 1 chocolate. Her name is Hershey, of course. Anyway, for 3-4 weeks I've noticed that sometimes Hershey stops, lifts her head and breathes in deeply through her open beak. This may go on for 2 or 3 minutes. During that time, her eyes close quite a bit. She also makes a little squeaky sound that may be a sneeze. Not really sure, since I don't know what a chicken sneeze sounds like. But it is very frequent. Today she was doing the weird breathing think a lot more. But not constantly. She seems just as energetic as the others. Is growing at the same rate as the other orps. She's eating and drinking well. I gave her a few drops of PolyViSol this morning, just for good measure. What do you guys think? Is she just a weak bird? Does she have some horrible condition? Is it going to spread? I'm almost afraid to even ask after a bout with Cocci took out 4 of my birds a couple months ago. But I don't want to ignore it and lose her, or more than just her.
