Hello there. I keep a few chickens, but in my dreams would like a few goats, a rescue donkey or two and an old orchard! A friend gave me some fertile (hopefully) eggs and they're coming to 21 days. Homemade incubator so have no idea of success rate. Interested in discussion on chick feed though. But also can anyone advise on incubation period? Husband refuses to believe it is 21 days exactly!
