So my broody hen hatched out two chicks on Saturday. I got to the feed store as quickly as I could and purchased two chicks yesterday and put them into the nest box with the hen. She did fine with them all evening and then let them sleep under her last night. This morning, both chicks were hiding in one of the nesting boxes and when I put them back with Mama and her two, she chased them. What did I do wrong? I'm really disappointed!! Can I try again?? Her chicks are little black cuties with white markings and the chicks I purchases are white easter eggers. Could the coloring variation be the problem?
