Hard Seal is an interior grade product, so not formulated to stand up to the weather and temperature changes for an outdoor application like a chicken coop. Provided your pressure-treated wood is seasoned (has dried for 6-8 months) and can take on a product we would recommend AFM Safecoat EXT Exterior Polyureseal Clear instead. If you are unsure how dry your pressure-treated wood is, there is a straightforward test. If you get the wood wet with water, if that water beads on the surface of the wood that means the wood is not dry enough to take on more product. If the water soaks into the wood, then your wood is seasoned and you can paint or seal over that.
