I have a batch of 5 week old hens.....I then got another batch of hens 2 days later.....one been who is 8 weeks old (buff orph) is picking on all of them! I have read order is what they do, but when will it stop?! The others are terrified and hide in a corner. I've put the buff in time out quite a bit, but she's still doing it. Will she hurt them badly?
