I have 2 hens brooding the same clutch of eggs. There are 13 eggs in the nest and they both want to brood together. Should I let them? Will they hurt the babies being together? Should I separate the two of them and give them both some eggs or should I let the one who first started brooding have the nest(one hen started 3 days before the other)? Any help is appreciated, also will they get lonely? Should I have a rooster in there for company?
