I also raise Phoenix. As long as their eggs are hatching at the same time they will accept each other's chicks and probably team up to raise the chicks together.I don't touch my Pheonix nests. The only interactions I have with them are feeding and watering. If they hatch, they hatch. I was just more concerned about one hen possibly attacking chicks under the other hen. The eggs are all the same age. I'm able to seperate the mean hen away if that's what needs to happen but I don't want to if I don't have to
