I ordered 10 silkies from Ideal Poultry in March. They are 19 weeks today. Out of the 10, I have heard and witnessed 8 crow. They had all been together until Sunday. I separated 5 of the roosters and took them to my moms. Everything was fine until this morning. One of them was being attacked by the other 4 so he was hiding. She removed him and we tried to place him back with the others, but they attacked him again. I brought him home and placed him with the 2 hens (hopefully because they didn't try to attack him) and the other 3 roosters. They immediately jumped on him. I grabbed him to get him out, and one of the "attackers" was chasing me and pecking my foot. I took him out for a few and then placed him back in with them. After a couple of "interventions" they are now playing "nice". IS THIS NORMAL??? I know I am going to have to get rid of 3 roosters since I only have 2 hens, BUT for now, any suggestions?????
