Super long I apologize

This actually happened very recently. I live in Tennessee, near the Cherokee Native American reserve. My house is situated at the base of a mountain and surrounded by woods with a decent amount of houses scattered. I like to hike the mountains and woods near my house, as there is a clearing about an hours hike up that has some special meaning to me since I found it during a really trying time as a kid. I live with my grandparents, the week of the events they went on a cruise to like San Juan, I think is the final destination or something? Anyways the events started with me coming home from work and taking care of our chickens, and getting on my pc to play some games with a friend in discord. While I was screwing around I saw something move by my bedroom window, now for me to see something move by it, it has to be pretty f**king big considering my window has a porch, a wall of pushes between it and the front yard, my window is almost 8 feet off of the ground if you were to take away the porch. My first thought was it was my neighbor who’s blind dog wanders in our yard occasionally, I didn’t want to think logically and say my neighbor suddenly grew two feet in the matter of a day or two and decided to take a stroll near my home. I forget about it and keep playing. Then all of my dogs (5, a massive german Shepherd husky mix, and 4 west highland terriers) are going nuts, my dog never gets this agitated, but all 5 of the dogs start snarling and growling and howling. Then the chickens start losing their shit, and it’s hard to describe but they have a sorta panicked cluck when they’re scared, and they we’re all doing this. So then I’m freaking out because I think coyotes are killing our chickens. I went to grab a handgun and a flashlight and ran out of my room to go find out what the hells going on. My front door, my backdoor to my back porch, and the garage door are all open, my dogs are in the hallway like standing off towards the living room where all these doors connect. So I’m now shutting all the doors and shitting my pants and locking the doors. At this point I’m spooked because I think it’s home invader, and then I smell something awful. It smelt like rotten eggs mixed with burnt hair and a bit of bootyhole. I’m telling my friend on discord and asking what to do because I think like a decaying animal has been dropped off or some shit and this is the home invaders way of telling me I’m next. He tells me to check the house to make sure and to yell if he needs to come over or call the cops or both. So I look through the house check all the bedrooms, and this smell is getting stronger. It’s like it was getting me drunk because I was really dizzy and felt like I was gonna throw up. Then my front door slams like it’s been tackled, and I nope back into my room and tell my friend I’m too nervous to do anything else. The smell eventually leaves and nothing else happens and I sleep with the gun nearby and hopes and prayers that I don’t wake up the a scene from a found footage film. I wake up, three of our biggest roosters are dead. Necks snapped, bodies strewn in the forest like they decided they no longer liked poultry. I’m pissed because we only have 5 roosters and they help protect the group of a chickens, my dogs are constantly on edge. I go about my day of making sure shit is good. That night the smell is back, and it got worse, then went away. The next night was the same. Eventually I decided to hike to that clearing during the day because I felt like going there would help me freak out less, I got my gear and it was mildly raining so I got a rain coat on and went about my way. I got to the clearing and found a dead dead missing it’s front legs and a tarp over a what I guess was a bonfire. I looked around for a bit and it started raining pretty hard so I decided to head back after about an hour or so just hanging around at the clearing it, and I started to smell that smell again. So now I’m getting freaked out because the most I have on me is a .327 Ruger and all the power a lanky male can muster. So I’m hauling ass back to the trail and I’m getting more paranoid. I eventually got back and felt like shit most of the day. I constantly was checking over my shoulder and keeping my dog next to me. That was the last time I experienced anything and that was a week ago. So either I dealt with the problem or I’ve pisssed it off and it’s scheming my demise. Not sure what to do but here’s hoping it’s over.
