Two things:
First, always use a tripod since you have a moving subject, and you need to have a solid platform helping to eliminate camera shake.
Second, don't try to "trap" the subject. Either trying to capture the subject in a tight zone, or allowing the subject to enter the focus zone, is futile.
Think in terms of trap or skeet shooting. Start behind the subject, and overtake it. As you cross the subject, trip the subject, and keep moving the camera with the subject even after the exposure. In fact, you should make multiple exposures following through.
Distance is your enemy. At 100 yards even 270mm is just not close enough. Around 8x to 10x a focal length of around 50mm is probably where you want to be.

I have a Nikon D3100 with a Tamron 18-270 Lens. I use the VC always but I can't get a sharp photo. I only photograph wildlife. I admit I need a lot of help with camera settings but I'm wondering if I can expect the lens to do a good job at 100 yards. I live along a river so that's about as close as I can get.
Thank You for any help!

Thank You!
Thank You!
You asked about getting a "Crisp" photo at 100 yards. Yes if you're photographing a Moose / no if you're photographing a Robin. For Birds In Flight (BIF) you will need a fast shutter speed; how fast will depend upon your ability to accurately track the bird- 1/800th should put you in the ballpark. Here is a tip that I believe you can use - If the bird fits into one of the Focusing Squares of your camera, it's too far away to get anything usable ... don't waste your time. From you postings it looks the birds were too far away for the lens you are using / it also looks like either or both the shutter speed was too slow/ your tracking wasn't very good. The good news is … with practice you will learn what distance will give you a "Crisp" photo and also your tracking will improve. Practice on anything that moves - low flying aircraft / passing cars / large birds (they fly more slowly and generally reasonably straight). Good luck.

Here is the dxomark test of your lens on a Nikon D3200.
As you can see it is not possible to take a sharp photo with this lens.

I found a lot of my focus problems are actually camera Shake also and not actually a focus problem

If you can get near water where there are seagulls they are very challenging subjects to try and practice tracking and shooting. Even with a great body and lens they are tough, but they will be closer to humans than many other birds. But forget using a tripod or monopod to track and shoot them. Handheld is faster and easier.

Are you using spot focus flogging he camera pick the focus point? I also think to are pushing your luck using a 270mmm lens at that distance; I use a Tamron 70-300 mmm and often get similar results. Are you sure the camera s rock steady? It could be a camera shake problem too.
Sorry for the typos. Should have read"... spot focus or letting the camera... "

I would try using back button focus and a single point of focus for autofocus this has helped me
