Hey man, I've watched your videos and read your posts and would like to offer a few pieces of advice, because I don't want you to take a bite. It's not good for you or the hobby, not to mention the people that care about you(and if you don't have that, I'm sorry to hear it). I know it's already been mentioned but if you haven't already contact Joe Pittman on facebook
https://www.facebook.com/JoeVenom and ask for the North American Pit Viper Envenomation protocol. I believe you can choose either the folder or a flash drive.
Another thing I would suggest, sooner rather than later, is to speak with a physician and get an epinephrine autoinjector. You might not be allergic to atrox or copperhead venom right now, but everyday that goes by you're being exposed to all those venom particles floating around and your risk is going up. It would be a good idea to wear disposable gloves and maybe even a n95 mask when your doing cage maintenance. If you have a severe anaphylactic reaction to a copperhead bite, It will kill you faster than any snake venom. And it would be a good idea to get in touch with someone like Dr. Spencer Greene or Dr. Sean Bush and ask if you can use them as consultants if you ever suffer an envenomation. Because the physician at your local hospital has probably never seen a snakebite, let alone have the experience to treat it effectively.
Now, on to the next thing. Please wear proper footwear, every video that I saw you were either in socks or barefoot. Please put on a good pair of boots and a pair of jeans or even better get a pair of snake boots.
Next, there is no reason for you to tail either of your snakes. EVER. They are both small and can easily be moved by single hooking, and if that atrox was an adult you could just double hook it. Now I'll list some more things to avoid.
DON'T open or close a cage with your hand, always use a tool.
DON'T put your hand in the cage if the snake is in the cage.
DON'T do anything with a snake if the weather is bad. If the power goes out, you don't want to be standing in the dark with a snake on a hook.
DON'T ever work with a snake if you've had something to drink, taken any kind of drug, if you're sick, if you're angry, if you just broke up with your GF, if you're in a rush or if you just feel off.
DON'T work with a snake by yourself (if you can help it) if you live with someone wait until they're home.
DON'T ever try to pin a snake behind the head.
As far as the cages you have, they're not ideal. Never put your hand on the screen, and make sure anyone that comes in your house doesn't either. Does it have a lock? If not, get one. A better cage would be something like a vision cage or maybe black box. Front opening, vents on side or back and lockable. And put warning labels on any cage with a venomous snake, along with the common and scientific name.
Last thing for now, you don't need to take your snake out daily. If there is not a reason to take the snake out, leave it be.
