I have 7 chicks. 6 of them I ordered online,but 1 I got a feed store. It's supposed to be an Ameraucana pullet. Not sure if it's a true Ameraucana, but I'm not worried about that. It seems to be the same age as the rest of my chicks,but it's tail feathers have grown in much slower than the rest of my girls and it seems kind of aggressive towards the others. It may be too soon to tell, but I thought I would ask.
