Okay,this might sound goofy but here goes. It's raining here- alot- I mean like a cow whizzin' on a flat rock: its coming down hard. All day. So my chickens are playing in it,running around happy to eat the warm oatmeal/sweet potato breakfast,but not acting like they even know they are drenched. Temp is mid to low 40's. My hen house door is open and the vents on 3 walls not covered. It will be raining and only in the high 30's or low 40's for the next few nights. Should I be concerned? Close the door? They roost inside the hen house and have an enclosed yard.. is being wet gonna make them get too cold?
