Our rollout nesting boxes work very well. Haven't had a single cracked egg or problem with them. It's far easier for the grandkids to gather eggs if they don't have to open the coop and go in, risking having to chase down escaping chickens all over the yard, when they are chicken sitting for us. As soon as the weather is better, you can bet that I'll have the insulation out of the outer gathering access and be back in business with the rolling nest boxes.
