i have a 2 month old Polish chick that got out of the chick pen in the coop and was beat up by the year old hens a while back. she has been in isolation since but is all healed up nicely and i think it is past time to put her back with the other chicks (13 others, same age as her). i'm a little worried about just putting her back in the pen with them, since she is my only Polish and i know sometimes someone who looks so different will get singled out and picked on. i don't know if the 2 weeks she has been away from them will have been long enough for them to forget that she is one of them. any advice?
