In a few months i plan to let one of my hens hatch some eggs for the first time, and I am wondering about a few things: - is it okay to hatch eggs from a different breed? (i don't have a rooster, so plan on buying fertile eggs; she won't abandon the chicks if they are a different breed?) - how many eggs can i put under her? (she is a buff orpington) - i plan on separating her from the flock, but is it possible to put her back in with the flock once the chicks are a little older? (is there danger of them getting pecked to death by the other hens?) Thanks!
