My husband and I are planning to start building our coop this week. The run is already complete (8x12). We have six chicks, 4 weeks old. We plan on doing a 4x8 coop, lifted off the ground. It will be outside of their Existing run, so we only plan on it being about a foot off the ground. We live in western Kentucky where the summer is hot and humid. Our winter is very, very cold at times- we see snow a few times per month. Any suggestions on wether I should insulate? How many & how big should the vents be? I want them to be happy & healthy of course! And for fun, here's a pic of my girls.
