I hatched out some silkies that are currently a week old I’ve already lost 2 and they’ve had the same symptoms the start limping on one leg then holding their wings out to balance and then they get increasingly worse until they’re weak and cannot move then they die. The one that is currently sick is limping but still eating and drinking and I have no clue where to even start. They were eating medicated food so I thought possibly thiamin deficiency they’ve been on purina non medicated chick starter for about 24 hours and now this one is limping when it was fine last night. The only thing I’ve done so far is add poultry cell to their water and I just did that. Someone please help!
