What about putting horse stall mats down to cover the slats and use shavings or straw. I use pine shavings and just pick out the dirty spots daily, turn it all over and add more shavings as needed. I only clean it out completely once a month maybe longer. Do you have food and water in the coop. If so I would take it out.Well I to I'm getting frustrated having to clean this 4' x 3' Duck house raise off the ground, it's inside a enclosed pen. The floor is wood slats. I lay two large garbage bags down then two large rubber shelving mats, so they don't slip and then straw. When I clean which is every other day it's totally poopy and I only have two magpie ducks. I roll it all up dump the straw in a wheel barrel and rinse off the garbage bags and the rubber mats and hang to dry. I have a second set of bags and rubber mats to change out. I rinse the floor out with a hose cause they do get poop on the sides of the inside of the house. I can not picture doing this in the winter! There's has to be a easier way! Any good idea's anybody???
