When I first got my chicks I got 6 of them at once from Tractor Supply Company, all around a week old, and when I brought them all home they seemed to all be perfectly healthy but when all the others started growing feathers this one just grew a few small ones and quit. Well after about 2 months this one never grew after around 3 weeks old and all the other chickens were fully feathered and healthy but this one was just pitiful and tired acting and it wouldn't eat or drink. Anyone have any idea what it could have been?
