I got a new rooster. He's a little over a year old and is used to being in charge. I have him separated in his own section of the chicken yard to keep him from my 23 girls. The girls are 6 weeks old. The other day when I was out with my girls I let him out of his area for some supervised visitation. One of the girls went up to him and pecked him in his wattles and he pecked her on top of the head and then kicked her out of his way. Then he went running after some of the other girls doing the same to them. I'm sure he is probably setting the pecking order straight but I think he could hurt my girls. I had him out for only about 3 minutes before I had to put him back in his yard. Is this normal behavior? Should I keep him away from them until they're full grown?
