i am going out of town friday mid day and wont be back til sunday. my 3 hens like to sleep on top of the coop (who knows why) but since its been cold i put them inside it. i am in alabama and it is supposed to be 44 to 45 degrees at night while i am gone. will that be ok for them to sleep on top since i wont be here to put them in? also they free range unless we are gone if i have to run up the road for a few minutes i leave them out but other that that when we are home they free range. will they be ok staying inside the pen while we are gone? the pen is 8 and half wide by 19 half long give or take a few inches. its completely closed it top to bottom. so will they be ok in ther pen? i hate for them to be enclosed all day but i cant help it.
