So I have been raising 6 [4.5 weeks old] chicks. The chicks have been doing fine on their own and they have a heat lamp that is mounted and a descent shelter. They live outside already temps have been higher than expected. I acquired a buff orpington, 18 months old, and they are reputed for being good mothers. I decided to add in the orpington directly to the flock of pullets. They have a coop of their own that is over 50 sq ft. There are no other adults. I check it daily for any issues as well as food supply and water supply/ice. I don't expect a mother/child bond to establish, but I am wondering if my chicks will be safe with an adult hen in the mix. Since it is an orpington, will it just leave them alone?
