I am having an issue with mice and squirrels getting in the run eating food. I use a hanging feeder so the mice eat what the chickens spill on the ground each night while the hens are roosting. I saw a squirrel in the run the other morning in the feeder with the hens present. I would have thought the hens would have attacked the squirrel but they didn't. I plan to add chicken wire to the welded wire to hopefully keep out the squirrels but that will not stop the mice. I am considering building a bucket trap for the mice and burying it in the run then covering it during the day when the chickens are out. A better designed feeder that doesn't allow the hens to spill so much feed would also be helpful. I have 15 hens now so I need a feeder or feeders capable of feeding 15-25 birds.
