Hi! I'm new. I have the chicken bug but I've never owned them before. I am thinking of building a coop, so many ideas here! Thanks for all the info I've already absorbed by lurking. I want to use recycled materials to build my coop. I came across a door like this: I wonder if this would be good in a chicken coop? It would provide ventilation. But would it be too cold in winter? I live in Upstate NY. Also, is it predator proof? What about with some hardware cloth over the louvered part? Just a thought. Thanks for any insights.
