Shortly after the chick got out of the egg, the Mama looked at it like "what's this thing" and got off the nest (another egg still unhatched) and started making the "bawk, bawk, ba-bawk". I moved my hand near the chick and she came after me but I'm not sure she has a strong maternal instinct. Is it possible she's going to abandon the chick? I have another broody and wondered if I could put her on the remaining egg and sneak the chick and shell under her tonight. That is, if the Mama isn't going to be a mother. Is this unusual behavior for a first-time mother?
