My pen of female chicks will be five weeks old on the weekend (3 days from now). My roo has been next to them for about three weeks so they can get used to each other through the bars. My females seem quite taken with him, queing up to be closest to the side he's on. However on a very brief test today they were happy to see him without bars until he started trying to chase and mount them and then they were very upset! When can he go in full time with them? I was thinking when they are 6 weeks old. They are still going to be scared at first! Do we just have to let them get on with it whilst he settles in?? I guess he would calm down after the first excitement of having new females? He still has his original partner so he hasn't been totally going without!
