I have 7 silkie chicks. Five are white and about 3weeks old. Two are blue and maybe 1 week old. The two little blue peeps have their eyes shut alot or maybe just one is open. Can anyone tell me what's wrong? I've had about 30 banty chicks hatch so far this spring and their eyes were open when they hatched. Oh, by the way, I bought these silkies at an auction. They all are healthy looking,even the two little ones.
