I work full time and can only collect eggs once a day when I get home from work. I'm wondering if I get some heat tape and line the nest boxes with it, if it will keep the eggs from freezing during the day. Will it make the hens want to linger in the nest boxes because it's warmer? I know it's designed to keep water pipes and such from freezing, but I don't really know how warm it stays. Any thoughts? Anyone ever tried this?
