I am new to backyard chickens. I recently acquired a coop and six pullets, 3 Barred Plymouth Rocks and three RI Reds. When it is cold at night (below freezing), all six of them pile into one 14"X14" nesting box. So far, they haven't smothered and they seem fine with that arrangement. When they start laying, are they still going to want to sleep in the nesting boxes? We have a new roost that is higher than the boxes. The roost that came with the coop isn't higher than the boxes, and they have chosen to sleep in the three boxes since the day we got them. I just hope that when they start laying they'll use the boxes only for laying eggs. How can I assure that that happens? Will they find the new roost and sleep on it, or will I have to close off the laying boxes for a night or two?They should start laying after the first of the year.
