I know that most people don’t recommend heating the chicken coop however I have a coop that is 8 ft by 12 ft and 6ft tall and there are only 2 ducks living in it so this winter heat is most definitely needed. We live in an area that gets extremely cold. I have been looking at a few different heating options however wanted to get your opinion on which one is safest. I was looking at oil heaters, flat panel heaters, or possibly a natural gas furnace outside of the coop in an insulated box. If I got the flat panel heater it would need to be at least 400 watts. The natural gas furnace would be a lot of work to get set up however I think the safest option. Any ideas on how to heat a large coop like this safely.
