Hawk Hunting Chickens?

[D13]

So over the past month or so we've been having a serious hawk problem.
Back in October/November of last year we had some random hawk show up and scare the crap out of our chickens. This continued over the next few weeks; though this hawk didn't try to eat the chickens, it just stared at them and made them freak out.
Eventually the hawk just stopped coming and our chickens started settling down and going back to normal.
It started later in late November with Samantha, one of our golden comets, being killed very brutally by a hawk. We were devastated, as this was pretty new to us (The closest we had had was an owl attack the previous year - it was a baby rooster, but still).
We figured it was just a one-time thing and that the hawk would just move on, so, we disposed of the body and went about our business.
A few days later it happened again, this time to Tiny, a young cockerel Cochin that one of our own Cochin hens had hatched out the beginning of the year.
Tiny's death was by far one of the hardest for me, because Tiny was one of my favorites out of the chicks. He was very cute and cuddly and looked very similar to his dad, Tiny Beak, who had died to an unknown predator in the months prior to Tiny's hatching.
At this point I was starting to get upset about this, because it felt like a hawk was...targeting the chickens.
I'd never heard of a hawk doing this; I just assumed that hawks would be constantly moving and so it wouldn't be a problem but NOPE.
And it kept happening.
A few days later Paprika, one of our newer Barred Rock hens, failed to return home. No sign of any attack, but I doubted she had gone to live with the neighbor's chickens.
Literally the day after next, Eve was gone (Another Barred Rock hen).
This time it wasn't until the next day that we found a body, and when we did, it bore the same marks as did all the others.
A few days later Meep goes missing.
THE NEXT DAY (At the time of writing this, yesterday) Nubs, our LAST NEW BARRED ROCK HEN, is discovered the same way as all the other victims a little ways into the field. (Same day we also found evidence of Meep dying to a hawk as well.)
So does ANYBODY have any ideas as to what we can do to deter this relentless flow of attacks?? I am getting REALLY sick and tired of finding my favorite little hens dead all over the property. We've been keeping chickens for nearly 6 years now and just a few months ago was the FIRST TIME we'd ever had a hawk attack.
I am at my wits end with these little pieces of garbage and would REALLY like some advice on what to do.
My parents are also really fed up with this happening, cause we spent some good money to get and take care of those chickens. It took us nearly 6 years to build up our flock to what it is today and over the last WEEK it's been halved.
We have 4 roosters (Smokey (Jersey Giant(?), Cornelius Junior (Smokey's son), Britches (Blue Cochin), and Big Guy (Blue Cochin)) and...I lost count of hens, but we have ~25 chickens total (I'm bad with estimates).
So, has anybody else ever had this happen to them? If so, what did you do?
Please share anything you can; we're getting desperate. Keeping chickens has been the best thing we've ever done, and we love all of our chickens so much.
All answers will be appreciated.

The hawk has found a good food source and will continue to hunt your chickens. You need to have a secure run and coop so it can't happen. That's the only way to stop it. Eventually the hawk will move on once the food supply is put out of reach.

Cover the run, keep the chickens locked up. The hawk is being a hawk.

Yup. That's pretty much the only answer that is guaranteed to work. Predator secure coop and run will ensure you don't have more losses. There are other things you could try, but they may have varying degrees of success over time, and you would be gambling with your chickens' lives. Don't know where you are in the world, but in the USA it is illegal to harm or shoot the hawks. The only thing you can do is restrict their access to your flock.

If you're not willing to accept occasional predator losses, free-ranging your chickens might not be the way you want to keep them.

Sorry for your losses. They always get your favorite ones first.
