Anyone know how to keep wild birds out of your feeders? I have a feeder in the coop and one outside for the ducks & chickens. I looked outside a little while ago and there must have been 20+ wild birds doing their very best to eat all the food. I have accepted that the crows/black birds eat the leftover dog & cat food, but that is after the animals have a chance to eat (I feed the dogs & cat at night). But I can't afford to feed every wild bird in the neighborhood. A few I don't mind but 20+ is too many. I moved the outside feeder into the duck hut but I can't keep it there all the time. I don't want to get a fake hawk or owl because I don't my girls to get used to a sitting hawk/owl and become used to the sight. We have both REAL predators here. Any other suggestions, please?!
