My son hatched chicks in science class and was able to bring 2 of them home. The 2 that we got were a hen and a Roo. They were told that they are RIR chicks. They are now out with the other hens for about a month now. Problem is that the Roo just started attacking us. Before we put him in with the other birds he was fine you could hold him and seemed to like us more than what the hen did. Luckly the first time he attacked me I saw him coming becasue I was kneeling down gathering the eggs and he was coming straight for my head. I have knocked him down when he charges at me, have tried to hold him but he bites. Its to the point that even if Im walking on the out side of the run he flies into the fence trying to get at me. What should I do? Thanks for any advice on what to do with him.
