Since I used old pallets for most of the walls I painted using a barn paint and for the trim a paint I found marked down to $5.00 and got a $5.00 mail in rebate it helps the wood last longer and makes cleaning easier we are going to use shower stall walling for the inside of coop so we can just spray it down and dry we used the recycled flooring (the kind that does not rot or anything like that) makes cleaning faster.
