I know this is an old thread but I want to add a question to it. I have a broody hen setting on 4 eggs. They are to hatch on 16th or 17th this month (March) I have a small hatchery close to me that may have some keets for sale at that time. Can I stick some under the Mama? If so, how many could I do assuming all four of her eggs hatch? I know you are to do that at night. I have already put other feed store chicks under a Mama that hatched out some two weeks ago with success. But since I'm doing guineas under a Mama chicken, is it doable? I need advice on this please. Thanks
