I have a chick that seems sickly. She's all fluffed up and mostly sleepy. She's about 5 weeks old. They're already in a coop but they'res so many chicks I figured they would keep each other warm. Which has been going great. All survived 35 F a few days ago. I'm keeping her separate with another that WAS sick like, she's currently doing great but the other one still is very sleepy. She's eating and drinking fine. She's very thin though, 2 died this morning so I'm not sure what that's from, I figured the space was to crowded and they were trampling each other since they've been doing that lately.. I just put them into a bigger coop today. Not sure if she was just cold? I have a bunch of other poultry so I don't exactly want anything going around my flocks. Thanks for any help.
