I'm wondering if a big (safe) mirror across from a window in a small coop might help reflect light and maximize whatever light is available if the coop only has a single window. Then I also wonder if a big mirror might drive the chickens crazy if they were in there and it looked as though there was a whole other room of chickens they could see - would it make them feel crowded or threatened or unsettled? The times they would be in the coop while its light out would probably be in bad weather so they might be a little unhappy at those times anyway. I want them to have as much natural light as possible and I know adding a mirror across from windows in houses can help with that. What do you guys think?
