I have 8 RSL that will be 1 year at the end of the month. We started with 4 nest boxes. They only used 2. Now we have 3 nest boxes and they mainly use only one box but occasionally we get an egg in another box (our guess is that is when the other box is occupied). I use hey in our boxes. Everyday I go out and they have pulled all of the hey out of all of the boxes and spread it on the floor of the coop. Even in the box they lay in. I replace the hey and they do it again. This morning I went out and they have a thick layer of hey on the floor and nothing in the nesting boxes. Am I doing something wrong or are they just being mischievous?
