I was given these chicks 9 weeks ago. so far they haven't grown any. I had purchased chicks 1 week ago that have well surpassed these chicks. there are five of them. maybe these are bantams but i have no idea what they are. maybe would help me care for them better. I have let the purchased chicks out in the yard but these are still so small they
stay in the brooder pen. any help would be greatly appreciated.
