Background: I have a Black Copper Maran Rooster that is just under 5 months old. He started crowing about 2 weeks ago and has been mating the girls for about 3 weeks. Beautiful bird - just getting his colors. He came from a prize winning egg and I wanted to breed him over my maran hen for the dark eggs. Issue: I just got back from a weeks vacation - I've had no issues with him in the past. We had the flock locked up in their house/run for the entire week (usually they free range). When I opened the run and went in to water them - he attacked me. Did it 2 more times. I stood my ground and gave him a good wack - but he still seems to have turned mean. Question: Is it possible he has just matured a bunch the last week w/ me gone and is challenging me as the top dog now that I'm back? AND - When he loses that challenge he will mellow out? or is he pretty much 'Chicken Dinner'? RELATED: if he is just challenging me - is it possible he won't bother my wife and the kids? I've heard mean is mean - but maybe this is transient behavior. Our last rooster would get aggressive with the kids at times (if they scared the girls) - but he would never bother me. This one is coming after me directly.
