ok rhino liner is way too expensive, plus i got a free box of stick on vinyl tiles in the bathroom. I though abou the cold NE Ohio winter and how to keep them chicken tushies comfy warm. So this is what i came up with after two beer. I have leftover reptile heating supplies such as flexwatt heat tape in 3in and 12in, a UT heater pad and orange heat cable in various length so there all kinds of watt from 8 up 100Watt all on 110Volt. How hard and expensive would it be to rig up a solar panel system and what would kep them at 45-50F during winter timein a 3ftx5ft area. .It gets down to 10-15F from what i know so far. I thought of mounting the heat source behind a ceramic or porcelain tiles to work as a heat"battery" and to keep curious chookies away from the cable/ whatever. I could mount a little heatpad in the nest box, it was made for a 5-10Gtank. what do you all think ?? to xpensive? i tend to get carried away with projects , but its just wayyyy to much fun. My kiddos are already waiting for spring so MOM not Dad can build a no-tree house.
