I live in Western Michigan, first time chicken owner! I want to make sure the coop is perfect for winter. Can it have very small gaps between the planks of wood, or should it be very tight? The reason I ask is I am reusing wood that I get from work, that is already somewhat together, in a square shape, and there are very small gaps, and was thinking of just using these pieces as is, instead of trying to take them apart, because doing that will probably break most of them.
Thank you for your help!
