Here's my question. I have 4 laying hens and six 9 week olds. They all sleeping in the nesting boxes at night but on the roosts in the daytime. Should I cover the boxes at night, except one so that they will use the roost. My leghorn usually lays early in the morning so that's why I thought of leaving on open. The ten of them sleeping six of ten boxes. Thx for any advice.
