I just started myself and I chose to go into the shooter market. The startup cost is less and the market is larger. If you decide to do breeder market, from the research I've done, you'll want to track pedigrees, buy deer out of the "famous" or "currently popular" deer, so your talking more money for these deer compared to one that is going to do the same thing but not as well know. You'll want to get setup to take DNA samples of your fawns and have them certified, talking about 75 dollars a deer for the DNA testing and such. Lastly, you'll want to get into CWD and any other disease monitoring programs you can. Where as the shooter market, you'll just want to get good does that will produce bucks that will score 140-200+ that look like deer. My goal is to sell 2 year old bucks that are as close to 200 inches or larger. Hope all works out for you whichever way you go.
