I have a black tailed buff jap that went broody a few weeks ago and now her eggs have hatched and then left them sometime last night. She left because her nest was on a countertop so I moved her to a more secure place on the floor. she had 2 bantam eggs and 1 standard egg.. The standard egg had hatched and was out and was so cold and the bantam eggs hadn't hatched yet and I only hear 1 in the bantam eggs cheeping but i could be wrong
So I put the chick and the eggs under a buff orp hen and she took them.
Will they live? do I need to do anything extra for them? PLEASE HELP!!
