someone in my coop has decided that the hay in the nestboxes does not belong there and is pulling it all onto the floor of the coop. I have not caught anyone doing it but I refill in the am and by pm, the box is completely empty (except maybe a poo they left behind) I have tried just shavings in the box, that got emptied as well. I believe it's the guinea hens that are roosting in the rafters. my hens have used the nestboxes for yrs without a problem. I now have a few bantams, and young guineas in there that are last fall chicks and everyone else has been there. what do I do? Yes, tried the fake eggs, they dumped them on the floor and not to sit on them.
