One of my broodies hatched three chicks and then it looks like she pushed the remaining eggs out of the nest. Is that a typical thing to do? It looks like she's being a good mama to her three chicks. Also, how do you manage multiple mamas and chicks? I have three broodies in an 8x20' pen. Each has her own nest--one in a 3x4' wire crate of her own, and two others in a 3x4' wire crate with a divider in it. When should I open the crates for them to take their chicks out into the pen? How do the hens typically act toward each other when they mix?
