I've been trying to stop a pair of small finches from building a nest in my coop (on the door no less) for about a month now. I have torn down at least 8 nests, but they rebuild it. Now they have added eggs to the nest - a new one each night - and I don't have the heart to throw their nest out again. I sprayed the nest down with poultry protector for mites, before the eggs and it didn't seem to bother the birds, cuz they've added more eggs. I don't know what more I can do.
