Thanks for all the feed back defiantly should be able to head in the right direction, I have a long metal feeder with the holes down each side I think that may be it, there run out side is about 15x20 roughly and there coop inside is about 8x10. I haven't seen any rodent droppings but did spot a rat in our barn probably back in early spring but haven't seem him since and I keep the feed bags tied up and haven't had any holes chewed in them. I am going to have to switch to a different style feeder I am thinking.
