Grain fed deer are the best..
I don't think it's the grain he's concerned about. Likely the steroids.
I'd say they are safe to eat and no most those guys do not eat them anyways. Probably donate to HFH
If they used steroids they would never grow antlers. Increased testosterone cases antelets to harden, decrease cause them to grow.
Any insight on the "grow them big" process? Just a lot of protein and genetic manipulation?
Genetics and peak nutrition. The elite breeders have exceptional genetically traced does. The breeding you see now in short is a result of decades of historical genetic data on both sides of the reproductive equation
You don’t manipulate genetics unless you can changes gene sequence. Deer breeding and HF are two different things though
