LOL, out of my 6 hens, only 2 use the nesting boxes...the others plop 'em out on the floor...seems they always scratch the bedding away first, too! We put down plastic (it's sort of made like cardboard, but it's plastic) and haven't had any break yet. In the nesting box, we put in a piece of that plastic mat that's meant to be a door mat...it's got little spiky things so it gives the egg something to rest on. When it gets really gucky, we take it out and hose it off. One of the girls climbs in the box and scratches all the bedding out before she lays and the other gets in and picks certain pieces of straw and puts 'em in. Go figure! LOL
