It's always going to be better with a hen.Do you use an incubator or a hen? I don't know if hatch rate is better with one or the other but both times we had a hen. I personally prefer that as that way momma raises them and not me.
I hope that is the case for me. I bought 6 hatching eggs that were started in an incubator. All were developing at day 8 candling and were transferred to the broody hen.
