One of our chickens is a week older than the rest, and she was perfectly healthy and stronger than the others as the chick, although her poo was always rather runny, so we didn't get very concerned. Recently, though, I started noticing how much smaller she is than the other chickens, and she doesn't seem to eat much and drinks a lot of water. When I picked her up (after a large amount of chasing and frustration), I found that her chest area seemed very empty. I haven't isolated her from the other chickens, since I'm not sure where to put her and she's been with the other chickens for two and a half months and they all seem fine. After reading other BYC posts, I'm suspecting coccidiosis, but I'm not sure... please help this newbie! Here she is, posing gorgeously... she's an extraordinary flyer for a two and a half month old chicken! The small white chicken in the center is her. Remember that the chickens next to her are actually a week younger than her! Any help would be greatly appreciated. This chicken happens to be my favorite, and all the other chickens practically bow down to her, so I don't want anything to happen to her!
