I live outside of Boston and this is my first year with 6 Rhode Island Red hens. They seem to be faring well in the cold weather but I'm hoping someone can tell me a way to check the level of humidity in the coop. When the temp gets up about 32 and the snow melts, our air gets really wet and heavy in general and I'm wondering if there's a way to keep the air in the coop as dry as possible, besides the ventilation cross breeze up top. Bedding maybe? Right now it's Koop Klean bedding and I moved the heated water dish to the outside run. Thoughts? Thanks!
