I can't find a post for this topic so here goes. We live west of Ft Worth (Texas, that is) on the edge of a really small town with unimproved pasture on 3 sides of us. We have our horse feed and chicken pellets in 4 matching plastic bins that each hold a 50# bag of feed. They sit on pallets in a group in a open sided hay barn.The chicken feed bin had a widening crack on the bottom that we taped up with duct tape to keep all the feed from running out. Over the last couple of weeks when I've gone out to feed the animals in the AM and release the chickens to free range, I have found only the chicken feed bin moved a foot or two from the rest of the bins or flipped over if it was close to empty. This AM the bin was moved and the previously unopened feed sack adjacent to the bin was tore open on top, pushed down and the most of the printed part of the sack was ripped off leaving only the brown interior sack. I put what remained of the feed (about 40#) in the bin and realized the duct tape was totally gone off the bin bottom. Swapped out the chick feed bin with the hay cube bin which is uncracked and called it good. Now my question is - what is coming for the chick feed? Some of the chickens are in a wire coop only a few feet away and are untouched as is their coop. One of the other bins has sweet grain in it and it isn't touched. I'm thinking possibly a raccoon or two but there are posts about raccoons as predators doing major damage to chickens rather than just trying to drag away their feed. I know if I had a choice between chicken feed or chicken I'd go for the chicken. Our dogs are inside at night but haven't alerted on anything outside nor have we heard from the horses who have their corral only about 30' away. Ideas?
