Just bought a Little Giant heater base for my metal waterer.......but now I'm having fire concerns! My coop has many inches of 'dust-free' pine shavings on the floor. The actual "flooring" (below the shavings) is some sort of "pebbled", hard, white plastic composite material. I plan on completely sweeping away the shavings from the floor area where I'm going to put the heater base, but you know how chickens are.........scratch, scratch, scratch! ........they even "dust bathe" in the shavings sometimes! So imagine shavings will be flung around the floor of the coop this winter! Even if I were to build a wooden "frame" to enclose the base.......shavings will still be flung!! Am I overdoing it with the fire concern here? Any advice on using the heater base "safely"?
