Hello I’m new to this site (kinda, I reference this site for research and emergencies) and it with something rather sad. I just bought a pretty little Rhode Island Red from the feed store today and just an hour ago she died. She was around an adult hen earlier who didn’t take to her. I set her up in an old guinea pig cage so that tomorrow I could buy a new brooder bin (mine cracked) she had a red heat light on her. She acted pretty lethargic since I took her from the hen but I didn’t notice anything before that since she had been in the box. I provided her water with ACV and medicated chick feed but she didn’t eat or drink. She just laid where I set her. She was smaller than the other chicks I saw at the store. She didn’t look sick though. She pooped once and it was normal. I was on my computer and she squawked loudly and when I looked she was on her back with her wings outstretched and about half an hour later she died. She stood up once and looked normal for a second but then she stretched her legs and threw back her head. My other chickens are fine I just checked on them.
