I bought 6 black stars from a feed store, when I got home I realized that one of them had a almost bald spot on either side of its back.There was so many in the cage that the owner just grabbed 6 random chicks and I didn't really have time to look them over.Its been a week and I think they actually look even more bald now.It seems happy and healthy,its lively as all the rest of them.They are 9 days old now.Is this common?
