I have 2 RIR's a Leghorn and a Buff Minorca, and just got a Buff Orph roo. Which one of the hens do you think might go broody and raise chicks? Is there any way to encourage broodiness or should I look into getting a incubator to raise babies? My hens are about 15 mths old and have never been around a roo before. They seem to like the new roo and he has certainly likes them!!
