I have four Pullets and a one little Roo (all 10 to 11 weeks old) I keep them in the hen house during the night, and while we are at work during the day. They free range on the property from 5:00pm, untill they decide to go back in the coop to roost on there own at dusk. Anyways, my question is...I find on occasion, that the two small Buff Orpingtons hang out and play in the nesting boxes that are part of the coop. None of them will be producing eggs for a few more months yet, so should I block off the nesting boxes now, and then re-open them when they become of age to start laying? That way they don't use the nesting boxes as just a place to hang out, and cause bad habits when they do start laying.
