I have a mix of cross breed chickens eggs, guinea eggs and Peking duck eggs that I started incubating just 19 days ago, they started hatching yesterday. So far 7 chickens have hatched and a few have just started piping, two died with in an hour after they were totally fluffed last night. 3 are in perfect condition, the last 2 are staring to fluff and scoot around. I've never incubated before, I always let the hens do it the natural way until we started having issues with nest robbing critters! We have ducks, chickens, pigs, calves and of course are faithful mouse hunting cats that keep those nasty rodents out of the hen house. I am open to any comments that would help with the hatching, we want a 100% turn out as best we can.
