Hello everyone!! Very first post!! WOO HOOO!!! My very first chicks are to be delivered in 1 week and I can not be any more excited!! Doing lots and lots of research on the coop and run. My original plan is to completely enclose the run area with a little chicken door into the coop. Does anyone leave this open throughout the night and/or day?? I wasn't sure if this would be ok in the winter. They will be free range in the backyard fence when someone is home. Thank you so much!! And thanks for all the great info I've found on here!!
