Tomorrow I'm renting an egg incubator from a local farm... It's a styrofoam box with an egg turner and every thing else etc... It has this as an egg turner: My thing is... do they hatch on the turner? I would think the turner would not be good for the hatching part. what happens when they do hatch? i guess you would leave them be for the time period. but anybody used this before? Does it hurt the chicks?
