So I just started with my little flock and my alpha hen Pearl is driving me crazy. At first all the other girls would go back in the coop but I always had to catch her. Now they all follow whatever she does wich now means chasing chickens every evening before we can go to bed. Last night when I tried to round them up she was aggressive and flying at me!!!! Most of the time she really is a sweet girl except when i try to get her to do something she doesn't want to do. Ugh!! What to do?????
