I have 3 baby chick's one isn't doing so well. She's an ameraucana. On Thursday night I noticed she wasn't moving I removed her from her shared brooder. I gave her raw yellow yolk until I could get her some electolytes and vitamin supplements. I started her on the supplements Friday morning. She showed signs of improvement, she started to eat and drink more but she still couldn't stand. This morning on Saterday I noticed her left leg sticking out completely. She's not bending it or moving it. The other leg also sticks out but she moves it. She still falls backwords but she can hold herself up. She's 3 weeks old her brooder is 86° was in the 90s before. She was fine the first 2 weeks we had her. She walked normally she ate. Currently she's eating her grit and is eating medicated chick food again. She's pooping and the constancy changes from a dull brown with white to a carmel color. A large amount of droppings come out in one sitting. Her vent is clean but it looks swollen so I removed the original bedding and put clean t shirts. I still let the other chick's see her from time to time but they peck at her since she's smaller. The other chicks are diffrent breeds, they are much larger then her even though they were born 3 days apart. She started to chirp again and does it when the other two do it. I'll answer any questions you guys have. I tried to put in as much information as I can. Please help I'm a first time owner and just want to help her. Sorry for the bad grammar and spelling.
