Hi there, I’ve just begun raising some chickens and am having a great time. I started out with 6, however I lost 4 last winter. I just purchased 8 more, ISA browns, Rhode island reds, sapphire Olive eggers and sapphire splash. I can’t wait to start getting eggs. I do have a question. I had 2 older chickens and I have already put 4 of my new chickens in the coop, so far so good. I was afraid the older girls would pick on the younger girls. should I have separated them? Like I said they seem to be getting along, but in the future, how do you usually introduce new ones to older ones?
