Can I put both duck and chicken eggs under the same broody hen? I have a Buff Orpington hen that's gone broody and I'd like her to hatch out some babies. We have 2 Silver Appleyard hens and a drake and we have 8 chicken hens of various breeds with a Welsummer rooster. Can I put a couple duck eggs under the broody and then a week later a few chicken eggs? (staggering the setting time so they should all hatch at the same time). Has anyone done this before? Does it work?
