The deer use it until the hogs take over. I've seen hogs get on their back legs with their front legs hugging these gravity feeders. Pigs also clog the openings with mud off their snouts so nothing can eat. Those feeders are the On-Time "Buckeye" models, I wouldn't recommend them if you have pigs as they are too low. I only used one this year and knew better when I put it out, the rest of them are in the barn.Does that gravity feeder get used pretty good by your deer? Next year im looking to go to something like that to avoid my hog situation. Wasnt sure how well they take to something like that?
