Thanks Mitzi, I will give it a try. Did you put them in during the night or during the day?David, I just had a hen sneak off (under a pallet!) and hatch 3 chicks this week. I put her in a 4x4 pen with her chicks and stuck 3 of my 1 mo old Bantam Ameraucanas under her also, they'd grown up in a brooder. She shoved the whole group under her wings and by the next day you wouldn't have ever known her adopted babies hadn't been hen raised. It may depend on the hen, this one is an 18 mo old Cornish mix who'd never hatched eggs before. I think you'll have fine luck slipping the chicks under the hens.
