I have a 5gal feeder that I suspended in the outside covered portion of my coop. the problem is small finches or meadow larks come and eat my feed by the pounds. since then I have moved the feed into the coop, however the small birds now fly into coop, any suggestions? my coop is covered with chicken wire, but all it takes is time before they make their way through the small holes, even have found a couple dead tangled in the wire. what to do?
