Chickens usually pick the most private nest box..I have curtains on mine for privacy..Lol..They are still young so hopefully in time they work out the kinks...My one Pullet was breaking eggs too and now she isn't so clumsy..There are 6 nesting boxes but they all have the same favorite one lol. Although the one that was smashed was with 2 other intact eggs at the opposite end of the favorite one.
