My oldest girls are now 17-18 weeks old and I introduced some nest boxes filled with straw and a golf ball in each a couple of days ago. They weren't too keen on the boxes at first (understandably) but now they are sitting on top of (not in) the boxes and scratching out all the soft bedding within. They are well fed and are turned out for long periods during the day so I can't imagine its food or boredom. Any thoughts? Do you think they'll stop making a mess and start using them for their intended purpose eventually? Should I hang them higher so they can't just get in and scratch about for fun? Should I just buy traditional nest boxes? The current boxes are large totes with the lids on and a large nest box sized "door" cut in the side. Should I remove the lid so they have more headroom?
