Yesterday, I made nice nest boxes. Three of them. I watched for a while, the hens wouldn't go near them, but the roosters did check them out... (I have four 4 roos and 9 hens... I know... not good, but so far no problems.) Anyway, today I go back, and all the hay that I had them is scattered all over the run, the hens are no where near them again. The boxes are empty. Now my hens aren't laying yet, though they should be by now. Any ideas on how to keep the hay in there for the hens if they ever decide to use them and to keep the roos out?
