I have a 3/4" 4'x8' plywood board that has soaked up oil when it was stored. If this is used for a wall on my coop is it actually or potentially harmful to my flock? The oil has completely penetrated the wood and can be smelled up to 5' away. I know that it keeps water from penetrating the wood but is it toxic to the birds? If so I won't use it. I hate to be needy but we are in construction mode today and need (hope?!) for an answer quickly so we can use it or not. I know that BYC'ers are gonna come to the aid of a fellow chicken rancher!
