I've got two broody hens. We let one keep her batch and kept taking the others away. She hatched 2 and left her nest. Then we let the other hen sit on the leftovers and she hatched out 2 more, but they met their fate before we could get to them. I am currently watching two more hatch under a light at the house. Question is, once they hatch can I put them with the mama that is taking care of the first two? Or do I have to be the mom for the long haul? Thanks!
