Here is my coop and run and I live in central Iowa so we get wind, snow, and lots of cold. Specifically for winter: I covered the south facing Hardware cloth side with plastic and it backs up to my shed. The north and west sides back up to our 6 ft fence as an additional wind block. The run is to the southwest of the coop which means it is parallel to the fence and the shed. There is a large amount of hay with the bottom of sand, dried leaves, and stall pro. I put feed bags on the inside to help with any drafts I was able to find from roosts down. There is plenty of ventilation above them to carry out moisture. I have electricity to the coop for their light and their water heater but prefer to not have any additional needs for electricity. We are heading into our first below zero cold snap and snow and I'm wanting to be sure the chickadees are going to be fine while I'm out plowing snow. As for flock, I have EE's. Cochin, Ameraucana, Buff, and Bantam Frizzle Cochin adults. I also just integrated my 10 week olds which are mostly silkie mixes as well as a NN/EE. I already have one of my silkie girls that struggles with the 10+ temps we currently are having. Any suggestions are welcome and I greatly appreciate everyone's help to ease my mind.
