Good morning all.. I have a small flock of 3 juvinile chickens at the age of 3 months... 1 leghorne roo, 1 BO and 1BR Yesterday I got a much older hen, already laying, this new hen is very mean, even to the little roo, he RUNS from her. Last night I had to lock up the new hen in the coop in a large dog kennel because she attacked my little BO. Should I have gotten a chick the same age as my young juvies? Or will they eventually get along? I am guessing there is a pecking order within the juvies and the BO is top hen..but my roo is smaller and freaks out around this new hen. Oh what to do ? What to do?
