Hi! 3 weeks ago I got 6 hens, they were around 22 weeks old. Today I am getting 6 more hens, they will be the same age and I am getting them from the same place as the first 6. Any tips on how to integrate the new birds with the existing birds? My chickens are free range so there’s no run for them. When I got my first 6, I kept them confined for 3 days. I’m not sure how to do that this time though since my existing birds will need access to the coop.
