So, I have a problem with mice and little birds. They are stealing my chicken feed in the feeder. The mice get in the poop tray and die because of the poop they leave and from the chickens. Then the little birds get in the the coop and stand on the feeder and steal it tell I have to shake it again. I went from feeding them every two months to two times a month. I only have two of them. We already used rat poison away from the coop. But, it hasn't worked. Please give me your feedback. Thank you.
