I have a what’s supposed to be 4 month old Maran that’s huge. I got her and 2 polish chickens that are supposed to be 2-3 months old. The Maran is too big to be with the polish hens. She may even be bigger than my 3 year olds. Has anyone had a less stressful way of introducing new hens to your flock? They’re in crates inside right now and I may have to make two separate introductions based on the size of her. Pictures attached.
