I hope this isn't gonna be a long post. Want to give back story. We had 12 1 year old Golden Comets hens. Well a couple months ago some raccoons killed 10 of 12 of our sweet girls. We loved them so much we decided to get more. We currently have 15 4-week chicks in my space bathroom lol. My husband is now finishing up on our new coop. So here is the question. How do I go about bring them together when the chicks are old enough? Thank you in advance!
