HEChicken --that is great what a good girl. I think the same thing, it is a science to get the incubator right and humidity and heat and turning. I have watched many cluthces hatch and grow, this is how my gma did it. I guess they know what they are doing, that is the reason they are laying them in the first place right? I really hope at least one of my girls goes broody in the spring. If she goes broody in fall or winter even should she be stopped?
