I have two bantam cochin chicks, three weeks old. They are in with a group of 23 others, standard cochins, welsummers, and buff orpingtons. They are rather outsized by everyone and I see they are hanging on the edges of the flock so as to avoid being stomped on. I have two hens in the processs of hatching more bantie cochins, silkie and Mille fleur d'Uccles. COuld I add them to one of those groups in a while? Like when the new chicks are three weeks old? Will the broody attack the new additions? Would the silkie broody or cochin broody be better to try with? Thoughts anyone?
