Hello! I have a 5 week old chick that has been fine up until yesterday when she suddenly started having trouble walking. I was gone all day and when I came home she was laying on her back. I went to pick her up and she got up and hopped away, but I could tell there was something wrong. This morning, same thing, she was on her back and seemed like she was struggling to try and get up. I have brought her inside and noticed her sitting with one let extended out and sometimes her toes will curl. I've read that this could possibly be a vitamin deficiency, but I wanted to get some insight here. Also, any supplement recommendations that I could pick up at Tractor Supply or somewhere local would be great. Thank you!
