We are new to chickens and this is our first coop and first winter coming up. We plan on keeping the windows closed in the winter (though there is the option to prop them fully or slightly or to let them hang open, which gives it a little less than one inch hanging open) but have these vent holes at the top. Are these holes going to be enough to keep moisture out of the coop? For reference, we have two roosts + poop trays. One is directly under the front window (with window box), the other is behind the side window.
