I'm sorry to hear that but you have the right attitude. I hope you have gotten some eggs for your trouble. Be the least the new girls could do.I know, right! It's savage. I've integrated others birds into the flock with no problems in the past (and as recently as 8 weeks ago).
I'll just wait it out. It had only been a couple of weeks penned next to each other, so probably a bit early anyway. It's all a game of patience with chickens. I have the space and the time to wait. I'd like to have them integrated by the end of July if possible, but if not, c'est la vie.
