Help.. I have 4 Pekin hens all of the same age they have been living in harmony together since January with no problems.. the foursome were inseparable. The last two days three have taken a dislike to the fourth, being rather nasty they chase her, pin her and I just bullies and peck at anything they can grab. 3 on 1..!!! Even when they are free range they will still chase, it's been so sudden and I can't work out what's happened as nothing has changed. She is trying to keep out there way and I'm feeding in two separate areas so she's not to be bullied out of eating. What can I do? Will it settle? Although she seems fine and happy in a herself and eating well she is starting to look a little bit rundown.
