So I know heating the coop is a no go. My main worry is one of my girls is going through a rough molt and we are going to be in the 20s for the foreseeable future. Our coop is well ventilated and their roost are not the way of any breeze. Is there anything I should do for her or should she be fine? They're only 9 months so I didnt expect a molt yet but shes definitely going through one and hasnt laid in over a month.
