SNAKES GALORE

I was just at the new house a few minutes ago. I walked two bags of trash out to the trash cans by the mailbox, and decided to take a stroll through the barn to see if I could find a snake. Boy, did I.
The barn is full of junk that needs to be cleaned out this winter when the snakes aren't so plentiful. I walked through the middle and looked over the side of the one stall, and there about 3-4 ft away was a coiled up rattlesnake. I don't know how long it was since it was coiled up, but I would guess a 2-3 ft. It wasn't rattling. I had my phone in my pocket, so I called Aaron and he said I could either try to kill it with a shovel or shoot it with a gun, or hope it was still there when he got home and he would try to kill it. I chose to wait for him since I didn't like the thought of a possible ricochet from shooting the gun and I for sure didn't want to get close enough to it to kill it with a shovel. That would mean being trapped in a stall with it.
So I did the next best thing and went and got my 3 kids to come see it.
But, by the time I walked back to the house and made it back with the kids, it was gone. There is not much worse than being in a barn, knowing there is a rattlesnake nearby and not knowing where it is. (The kids never got closer than 15 ft from the barn, I wasn't going to bring them in until I found it.) But, while I was looking for the rattlesnake, standing at the edge of the stall, peering over the wooden planks, I look down, and about 6in from my feet (on the other side of the stall), was a coiled up copperhead. There was a plank in between me and the snake, so don't freak out too bad. It would have had to strike me between the stall planks, and it wasn't looking in my direction.
Apparently the snakes did the ole switcheroo while I was going for the kids. I chose not to bring the kids into the barn to see the copperhead, since the rattler was probably watching me. I also saw a 6 inch long lizard and a spider in a huge web, probably 3" in diameter- the spider, not the web. Although not poisonous like the snakes, the spider, by far is my biggest foe. And they grow them big in the country. I can handle snakes, and I would welcome them if they weren't poisonous, but the spiders, oh, I just can't handle that very well at all. Ugh! Any suggestions on a type of dog that will go after snakes and keep them away from your house?
By the way, Pump is in the well and pumping water to the surface, yes!!! I ran it for about 45 min. today through a hose into the yard, like the well man said. Said to run the water until the water runs clear. At first it was like watered down milk - getting out all the rock and sediment they drilled up while drilling. Once it is clear, we can get our sample to be tested. We can go ahead and have water in the house once it is clear, but we won't be drinking it until it gets cleared by the health dept.
