I have a 19 week old Buff Orph Roo. He free ranges with 5 hens. They have been hand raised,they are very tame and friendly. The last two weeks the Rooster has become SUPER aggressive. Last week he jumped up at a 6yr old and 8 yr old and scratched them on the leg. This morning we were heading out to the swing set and the chickens were about 200' away. The Rooster came charging over and attacked my 2 yr old !!! He jumped at her and she fell backworks and he was trying to jump on her again. I ran over and kicked him about 5 feet and he decided to back off! Is this normal?? He has been crowing like a mad man ALL DAY and I noticed him running after the hens trying to have his way with them..... Is it just his sex drive kicking in so he is territorial? If he keeps this up he is going to get his head chopped off!!! I cant have him attacking children. He wont do it to adults or to my 5 yr old....she will kick him....not afraid of him. What should I do???
