My coop has an enclosed run, the doves aren't getting into it but they are landing on top. No matter how carefully I place the treats and feed the chickens manage to kick some out, or my kids spill it trying to "help". The doves have figured this out along with a couple blue jays. I'm doing my best to correct the feed situation but are there any other ways to deter these annoying pests? It's well known around here that the mourning doves carry disease and parasites. They've been hanging out around the coop and the chickens seem oblivious but I don't want them that close to my girls. Thanks!
