OK, just one more question......I'm hoping to finish my coop tomorrow except for painting it.......I am not a master builder by any means so my walls aren't exactly square. Since it does get cold and windy here, I was thinking of using silicon caulk to make sure there are no stray drafts except for where my vents are -- especially on the north side. Will silicon caulk hurt my chickies? Should I use something else? How well sealed should I make my coop? Are a few gaps up close to the roof ok? It has rained a few times since I got the roof up and no water came in and my chickies seemed warm and cozy. Thanks for any advice!
