So, i got the chicks into the coop,and let them hang out for a week while i built the run. There is both a human door and a pop door to get into the run. i was worried that the human door would let too much cold air in during the winter,so put in the pop. They won't use it. it's only been a few days,maybe i should just wait,but is there a way to encourage them? If i leave the human door open they go popping in and out all day.
