Warren, Hackney said they use protein made specifically for penned deer. Don't know the brand or the percentages, but I'll see if I can get in touch with him.
He also said the protein they use has minerals in addition to the protein, which he believes is beneficial.
I'll post back if I can track him down. I know he's been back and forth to the property, and is tough to get in touch with when he's there.
