Oh, just get a big capital letter "L" tattooed on yer forehead and be done with it.
They are not "your herd", until you buy them all and have them ear tagged. And you can legally keep them inside a fence.
Taking pictures of them is not a thing like "Managing" them. Though by attracting them to your bait piles, you might just be helping them to spread communicable diseases all that much faster.
Eighty acres of Downtown Toronto, isn't a joke, but proclaiming all you have, for your 80 acres, is. Get all warm and fuzzy about providing a home for a wolf, when you own the 15000 acres next door. But still, don't get all teary eyed if the wolf gets shot by a neighbor. The wolf doesn't care about your property lines.
And your "Cull" did, well, essentially nothing, as far as the general population around you is concerned, as it did not a thing to remove any potentially bad genes from there, it certainly did not prevent other immature bucks from being able to breed, and it didn't take any of the perpetually dry does off the playing field either. You do not actually have the ability to "Cull" the deer in your area, as you cannot, at any time, or for any reason you see fit, destroy or ship to slaughter, any of the deer that you think do not meet the criteria you have set, are injured beyond recovery, or are underperforming.
I keep a "Cull" list of my flock of sheep. Bad Birthers, Bad Mothers, poor condition in good feed conditions, and a few other criteria, get them shipped to the auction, where they go for dog food or ethnic meals. That, is a cull. Removal for a good and obvious reason. Not limited by the number of deer tags one can get, either.
Despite your grandiose assertions, what you ended up doing, is shooting a random young buck, for no apparent good reason, and used up your tag on that, instead of on a buck with some meat on him. Or a dry doe that would have given you more meals.
