Yes, I have a bigger pen with 45 semi-wild deer that I recover from a property that was sold to build houses, I was in charge of that place for 8 years, and the deer were going to be killed or escape to fateful and unknown destiny, that was the reason I had to buy 20 acres on the top of a hill to put them to keep them alive. And I have a smaller pen for injured or orphan fawns, there I have my 6 favorite deer and 2 fawns.
I use in my supplement just ingredients like cereals; corn, sorghum, wheat, soybean, and melaza cane sugar, corn gluten and "Deer mix" a pack with vitamins and minerals specially designed for deer. I don't use any animal products, they may be viruses contaminated from sick animals. and I always try to make my supplement as similar as possible to deer natural feed.
The two feeders that appear in a garden are build by me, I designed them for feeding deer 24 hours per day, they only used gravity to work, and that way any shy or nocturnal deer have access to the supplement anytime. That is my house on the left and my brother's on the right.
I will send you some scenes from my deer and me interacting together, "love scenes", you may laugh of me.
