We have recently converted an old shed my husbands father built 20 years ago into a coop. It's previous occupant was a goat (20 years ago), and my SIL never cleaned it out a final time when the goat passed away She gave it to us goat poop and all, I cleaned it very well, but the walls are pretty stained. I would love to paint the walls put because I have moved chicks into the old coop, I really do not have any place to put the big girls while the paint odors fade. Can you use a no VOC paint in the morning, run fans all day and have them in it that night? Hindsight is 20/20, I really should have painted the coop while we were fixing it up... Thanks!
