I had my first incubator hatch 4 weeks ago, i have had hens sit in eggs in the past, my grandpa put some of his layen hens eggs in with some of my game bird eggs. his started hatching on the 20 day and only one of mine hatched until the 23 day then mine hatched. I was worried to death mine wasn't going to hatch. only 5 eggs didnt hatch I'm about ready to do it again. also I love your rooster pic
