The completion of my peafowl pen is right around the corner but I have a question. The entire pen will be recycled materials, including the wood. The wood is from pallets. I am wanting to spray a primer or sealer on the wood so that the wood doesn't rot. Is this ok to spray on the wood? Are primers and sealers hazard to peafowl? Will they get sick from it? Anyone else used a primer or sealer? If so, what's the name of it.
