I just have paint on my floor. 2 coats of oil-based KILZ primer, 3 coats of exterior latex. It's lasted 2 years in Minnesota with BIG temperature fluxuations. I am very happy with it's performance. When it's cleaning time, I just spray it with a bottle of vinegar/water, let it sit for about 5 minutes and rinse it clean. Presto.
BTW, if you really have 2 fully exposed sides to your coop, you might want to consider hardware wire instead of chicken wire. It costs more, but it's a small price to pay for peace of mind.
