I've had an incubator for a long time but I've never used it before other than when I had a broody mama get off her nest after half her eggs had hatched. Last weekend a couple coyotes got into the coop and took 10 of my 15 chickens including my rooster. I collected eggs for a couple days and put 18 of them in the incubator yesterday. I loved my rooster and I know he was doing his duty so I'm keeping my fingers crossed that we'll have a couple of his babies at New Years. I did get to use the saying "Don't count your chicks before they hatch" in the literal sense with my 6 year old. I laughed as I said it.
