My dominant Marin hen , approx 1 y/o, got broody on Friday and the next day her companion did too. I think she's being a" copychick" but in any case I left them in the nest boxes inside the coop last night with no hay to make it a little uncomfortable and today placed them in a wire cage with the fan on in the barn. 2 hours later they both wanted out and haven't returned to the barn. If they do they will both go in the cage tonight.
