Our climate is too cold for the pop door to be opened for at least six months a year. Currently, I'm without chickens, but it is chick season and the question arises whether or not to buy some six or seven chicks and begin again. The indoor dimensions of the coop are 7' x 9' and yes there is ventilation, light, heat, roosts, nest boxes, windows. QUESTION: does anyone have experience with having their birds cooped up for a long period of time? What happens about pecking (hens only planned)?? A head of cabbage or flock block helps a bit, but I really want to hear about experiences of others whose hens are confined for months on end. Thank you.
