IME when fawns are big enough to jump a 34" hog panel they are big enough to eat of the tube style protein feeders. Does not do a fawn any good to jump into a pen if it can't eat out of a 37"-39" high tube. I saw some research that was done on hogs and panel height, it said that either 26" or 28" was the minimum height for almost all hogs and still allow fawn/young deer access.
I use 34" tall hog panels and my protein feeder tube height is 33". Fawns can't easily eat when they are finally able to jump in.
Thank you, I knew you would have some personal experience. I just wasnt sure if it would be worth it or necessary to have a lower tube for fawns or not. Was planning on the 34" panels but wasn't sure if I should make a few places lower for fawn access but sounds more like, when they are ready to get in, that's when they get the protein. BTW, love the pics you post. I always play the age game with your pics as I continue to try to improve my deer aging. I was fooled this year by some post mature deer that looked young everywhere except belly and shoulders.
