Oof. If he had been that aggressive it would be a lot easier to rehome him.
I should say the hormonal behavior started about a month ago. He may be a late bloomer (he is just now getting his spurs). If he is going to mellow into a good boy I'm willing to build him his own area (I can't have him in the coop with girls) but if he is always going to be like this? He's going to a ranch I found that will take him (and not eat him). I just don't know if he's worth the headache.
He has challenged me several times (I kicked him or whacked him and he quit and then avoided me) but it's always been in situations where I can understand it (ie: trying to mate, I was holding his favorite hen, etc) and never out of the blue. I just wish I knew how he would turn out - he's grogeous, an EE and absolutely lovely. And SO good with his favorite hen, finds her treats, sits with her when she's laying, etc. If only he would stop hurting my older girls it would all be ok.
