One of my Wyandottes appears to be sick. I just went downstairs to check on them, and she's got her feathers puffed up, her eyes are mostly closed, and she is sticking her neck out and opening her beak repeatedly without making any noise. She's also sometimes making a gesture that looks like she's swallowing, smacking her beak several times in succession. As I fed the others, she didn't come anywhere near, but stayed off to the side, puffed up and sleepy, and doing that weird thing with her beak. Six hours ago when I went downstairs, she was fine. All 5 of my chicks are 4.5 weeks old and the others are all healthy and active. What's going on with this little girl?
