I'm looking for a paint that includes primer to make less work for hubby to paint. He would like to leave as is(particle board), but I heard it's best to paint. I'm looking for a pratical color vs what looks good. I would like to do a brown because it would show less marks for the chickens to peck at on the wall. We have a light installed for the winter months at the top of the coop, which is 8 feet high right in the center of the coop. We are using a standard 60 watt bulb inside a cage for the bulb. Would brown be too dark? I personally like the looks of the particle board, so if you think I don't need to paint please tell me. Our coop is a room inside our garage, so it is weather safe and I would not paint the outside. Thanks in advance.
