My EE's are between 16-18 weeks old. The oldest girl was hanging out with the rooster in the nestbox today, so might not be too long until I can hatch some of those too. Since I'm down to one broody hen, unless the EE's go broody, I'll have to be doing most of the hatching now. It was nice having the broody hens do all the work. I need a better incubator. I'm thinking of just modifying my lg since i do like it. Adding more styrofoam to insulate it more, a fan, and racks so I don't have to turn one by one.
