I'm sure this has been asked before so I apologize in advance! A few months ago we were given 2 full grown chickens who have been together from very early on and they get along great. 6 weeks ago we were given a 2 day old chick who has spent her time indoors in her box, etc. we've recently started trying to introduce the chick (supervised of course) to the big girls since they will be sharing a coop. Our the silkie is indifferent to the chick, but the speckled Sussex gets very aggressive with her and has pinned her down and pecked at her and will peck at us when we try to remove the baby from her area. She NEVER pecks at us, so that is very odd too! What can we do to ensure they will all get along? I'm worried that we won't ever be able to let baby in the coop with them and will have to get her a separate one!
