Well to everyones discouragement about not allowing the babies access or removing the nest until older, my chickens are all different ages 2 1/2 months up to almost 2 years and I have never had a problem. Each has their way of doing things, but my babies move to the adult coop at 2 1/2 months, they are tossed in and everyone does well. As for poop on eggs, keep the nesting boxes cleaned out and you do not have that problem. It takes me 2 minutes to clean out a box and it is well worth it to me.
