I have a 4 month old Dominique rooster. Right now I have him with 5 production red hens just because. He's always been a great rooster and nice as could be. This past week I went on vacation and had a buddy watch my chickens. When I got home I noticed their water was very low and I had 2 days of eggs. I called him and he said that rooster flogged him every time he went in there. Could this be b/c it's someone new or because he's going to just be like that with age? He didn't mess with me when I went in there today. I was also wondering how most people keep a rooster separated? What size pen and such? I have 12 young doms I'm waiting to get bigger but don't want him with them dummy time. Any info would be great.
