I have 20 pullets and 1 roo, black australorps, they are now all 15 wks old. Just this past week my roo has been trying to mate but the girls arn't having any of it yet! Should I do anything about it or is this normal for this age? Also, I have a few hens that put up a fuss when I pick them up. Hef will come running over and look at me and cluck until the hen calms down. Should I worry about this behavior? I always pick him up next, just to let him know who is the boss.
