correct on the low fat and minerals but deer do very well on them.
Blackbirds and cowbirds are really bad right now and will kick lots of protein on the ground also. Running cameras to see what the problem is for sure? Coon problems are usually in June when they start to take the young ones along to the feeders. If you have any grain or corn not ground up all the way into the protein pellets birds and coons will give you fits.
Ran a camera. Probably 60-70% coon pictures. Rest are deer. I'm sure a deer eats significantly more than a coon, but the coons are killing me. I used to be under the impression I was feeding the coons about 10% of the feed. Now I'm thinking that is closer to 50%. Had 8 coons at ones. Scooping it out on the ground, the party was on. One even took a short nap between meals.
