I have 3 store bought chicks which I purchased over labor day weekend..so they are approx. 5 weeks old. Two days after I bought them I found my 'lost' Buff Orp. who was sitting on 17 eggs. She hatched 14 mutt chicks on Sept. 12th. My 3 purchased chickens are in the barn with the goats and a warm light..my mama and babies are in one end of the coop partitioned off,with a dog house and mama to keep them warm. My question is..how the heck do I integrate all of them. Mostly I am worried about the purchased 3. They have no one to protect them...I am thinking doing the playpen method in the coop with a partition in the run for just them for a couple of weeks and then once they are comfortable, opening up the broody partition to let mama and her mob out. Any thoughts? Oh...I have 8 other hens and a Barred rock rooster to add to the mix.
