Ok, so I have been searching around and I know there are a ton of questions on this, but the answers always confuse me so much!! So we have a coop right now, that the previous owners of my house built and was using. It was poorly built, but works for now. We are planning on building a new coop (amazing the amount of usable lumber we have found laying around!) and we need to have some nesting boxes. The ones in the current coop are very obviously too small, since our cochin cannot fit inside it! How big do you need to make the nesting box? If we have several sizes of chickens, do we need different sizes of nesting boxes?
