Hi there, I am new to BYC and the whole chicken world and had a few questions if anyone can answer them. I have been looking at coop designs and have finally decided to design and build my own to suit my needs. I was wondering if the coop needed to be insulated; I live in west-central Indiana where the winters can be pretty cold and the summers equally as hot and humid, especially of recently. Otherwise I was planning on using plywood for the walls. It's only going to hold 3-4 hens, so the coop wont be too large. And as far as windows and insulation go im a little bit rusty, but I have a fairly good idea where to go on those aspects.
