I'm new here and am moving to VT this year and will have acreage with chickens to start. I am a multi tasking handyman, auto/truck mechanic and once while being unemployed, was even contracted to build a rather fancy chicken coop in the Santa Rosa area of northern CA. She wanted one offered at the local hardware store but did not want to pay the $2500 price tag. I took a few pictures, some measurements and copied it rather well for a heck of a lot less parts + labor than the $2500 they wanted. It was on 4 posts, and the floor was a couple of feet off the ground with a wire mesh floor. It was cold there in the winter, but not freezing all day long like it will be in VT. The question is: What is the difference between vented and drafty? How does one vent the place without causing a draft? I would assume keeping it closed off up high to keep the warmer air up there for the roosting birds at night.
