haha I never looked into that. I was trying to go the incubator route and decided against that until I can afford a self turner one and what not. I like the idea of a hen hatching them better anyways. So far all my chickens have done well. And Chiisai, I don't know if you get mites on your birds, we do horribly here, I was treating with Seven Dust and found to treat with frontline or advantage! It works for a few months at a time and works way better than Seven Dust. Of course, you can't say the eggs are organic. But I never claimed them to be in the first place. And it has no ill effects or transfers to the eggs being consumed either.
