My son put fresh bedding in the coop last week & now, most of the nests are emptied everyday of the straw! We put it back in, they move it out. Why? I have been trying to break them of sleeping in their nest boxes, but they still sneak in there to sleep earlier & earlier (now before I am home from work usually) So we also have to daily go through picking up hens & roos and putting them on roosts, before we can close the nests for the night & put straw back in the boxes. They typically lay 12 or so eggs in 3 boxes & empty the rest (7) of straw. I am beginning to think that they are just master manipulators!! Any ideas on this new, annoying behavior?
