My hubby bought some resaw lumber to put on as siding for the coop. Gonna out the rough side facing out I really like the rustic natural wood weathered look. I know it takes time for wood to get weathered & darker. This guy down the road said to mix kerosene & burnt motor oil & use it to stain the wood on the outside. I was thinking that might look good to make the wood not look so new, but I was concerned about the fumes from it hurting the chickens It would only be on the outside rough cut wood & it would be a day or two before they would even go in that coop. Is that ok? Or should I do something else?
