I have sixteen chicks that I am introducing that are 2 1/2 months old to four month old chickens. I did the 'see but don't touch' method for several weeks and now they are all together. One chick walks on her hocks and can not roost because one foot is sideways. My question is will she be able to survive with older ones? She is fine with her batch of chicks..There are seventeen older ones and sixteen younger ones.Thanks a bunch!
