We have a 22 week old SLW roo. He's our first roo and so far seems to be OK with the hens. He does two things around my DH and I that I am concerned might be a sign of future aggression. He lets out a warning cry to the hens every single time my DH or I enter their pen or the yard when they are out. He also will stand a ways off from me and rises up and flap his wings. He's never side stepped me (he won't get close) but he will crow his head off a lot when I'm around. Tonight I wanted to check on one of 'his girls' (he has about 6 pullets that are glued to his side all the time). When I picked her up off the roost he jumped down, stood in the middle of their pen and just yelled at me the entire time I was holding her. I decided not to put her down until he gave up and quieted down. He seems good with the hens (watches out for them, not too aggressive about mating) but if he is going to be trouble I will have no problem getting rid of him. We both work full-time away from the home so my time spent with him to fix any behavior issues is extremely limited. So, should I be concerned?
