My husband thought it best I create a new "indoor" coop inside his horse barn. This way my chckens will be safer, cooler (fans) and protected from misquitoes and flies (screens on the barn doors and windows). He also has an automatic fly sprayer over the horse stalls to keep the fly population down in the barn. I am concerned to have the chickens in the same barn as the auto-sprayer. He tells me that the chickens will be on the opposite end of the barn, maybe 30 feet away, so out of harms way of the insecticide. The barn is plenty ventilated and has screens on all the doors and windows, with a nice breeze blowing throughout. Any words of advice as to whether or not to put my chickens in the barn withthe auto-sprayer? I am not convinced that they will be safe.
