I once tried taking the chicks out the little window and kept burning myself. With my last ones I had 15 good eggs left by the time they were ready to hatch and all but the one that drowned hatched, so I was pretty happy! They started pipping Tuesday night, three were out Wednesday morning, six more Thursday morning, and the last four throughout the day Friday, I can live with that. If all my hatches will go that well I'll be happy!
