Hi everyone. With an arctic blast coming our way this weekend, I'm nervous about my young hens in their coop. My tractor has an elevated nesting box that is about 4 feet wide x 2' x 2'. Because the tractor itself has a door that I lock, I don't have to lock the chickens into their nesting box each night. But, this means that there is a big hole (about 10" square) that the chickens enter/exit through each night/evening. This big hole has to let a lot of cold air in. Is there any way I can make a "self-closing door" for their coop? Sort of like those funny old-school grocery store "doors" made of tons of hanging plastic strips. I was thinking about some kind of thin, flexible material (carpet?) that the chickens could push through to get into their box. I am trying to make the nesting area less drafty. I have a funny feeling that the chickens would not appreciate/understand this obstacle....anyone tried something like this? Am I being overly paranoid? I live in Oregon...we probably won't see anything below 15 F ever.... Thanks!
