I go outside to the outdoor run this afternoon and a few sparrows flew out. Not sure where the snuck in, but they did. It's a covered run, but still managed to find a way. Made a huge mess of the food. The neighbors have feeders out for the wild birds, so they out in full force. Any tips on how to keep them away? Don't think a sparrow trap would work with the the number of them around. I have a five gallon galvonized feeder that I could cover, but they would still be able to eat some of the food. We just got another 20 inches of snow and it's very cold out. So I'm guessing these little guys are in the search of some good food. But not ours. Any tips???
