I raised 3 silkie chicks from one day old. They ALL started crowing last week, so I returned 2 of them to the breeder in exchange for 4 babies about 2 months old. After about 3 days side by side "getting to know each other", I let him into their pen. Wrong move! He went into attack mode with intent to Kill! I took him out thinking that the babies were too young. No harm done, but I have a BIG PROBLEM. He is not eating enough chicken food to stay healthy! I am giving him treats which he may or may not eat. I spend a lot of time with him, but he is sad. Last night I put a red sex link pullet his same size and age in his pen. He immediately attacked her viciously...not your normal "pecking order" fight. Took her out. Does anyone have any suggestions? He is not aggressive toward me at all...I thought he was a sweetheart, but evidently his gentle nature does not extend to his own kind! Please share your expertise with me!
