About 5 or 6 ago we started our flock with 5 chicks (2 easter eggers, 2 golden-laced wyandottes and 1 black sex link), brooded them and moved them to the coop a couple weeks ago - Our weather has been warm, there was a heat lamp in the hen house and they were almost fully feathered. They've been doing great and getting noticeably bigger each day. A friend of mine needed to re-home a young hen and we took her in a few days ago. We've been letting her free range during the day (she jumped the temporary fence we put up) and our chicks are still in the run of the coop. At night the hen roosts in the coop but does not go into the hen house. Instead she roosts on one of the bars in the corner of the coop. She chases after some of the chicks and the chicks occasionally follow her around but then run away from her. They've pecked each other but mostly to get space from each other. It doesn't last very long and it's not super aggressive in behavior. Tomorrow I plan on throwing some scratch/treats in the coop and see if they start to warm to each other over it. Is there anything else I can do? Anyone with advice, suggestions, experience to share? Thanks in advance!
