I don't have a bator, and if I can get hens to hatch, I never will have one.What I would do is fire up the bator and complete the hatch that way. But my bator is so unreliable.
In general, I prefer to buy chicks. I have a menagerie of heritage breeds. My Ameracaunas (plus the roo) are not good examples of the breed and lay green eggs. (I SO wanted blue.)
