I have some eggs in the bator & 1 has a pip. I have a broody hen outside that is laying on one egg & I just moved her to a cage of her own. She has been broody for about 1 week now. Question....can I slip the pipped egg & maybe a couple more under her tonight to let them hatch under her? Or should I let them hatch & then slip her the chick(s)?? Any advise would be greatly appreciated.
