I got 8 chicks 4 days ago (2 Bo, 2ee, 3 silkies and 1 cuckoo maran) and 1 of the silkies isn't doing well. They're all a week and a half old and they're all fine except for her. She spends almost all her time curled up beside the feeder and peeps when we touch her. She doesn't have pasty butt, curled toes and I'm pretty sure not splayed leg. She substantially smaller than the other silkies too. They're on medicated feed and normal water. Please give any advice you have, I want her to be healthy!
