Two days ago I got my first shipment of Silkie chicks. Yesterday one died on me and I'm currently holding one on deaths door. Am I right to separate this chick? He/She can't stand and the other chicks are trampling it. I've done all the "right" things for this chick. It keeps opening and closing its beak. It's just so weak. Should I keep it separate or let him/her die with its chick brothers and sisters?
