There may be a better way to do it, but what I did was go to my profile so it showed only my Tweets, and then when you hover on the one you want it will show a few options including Open. If you select open it will show you just that tweet, and then you can copy the URL.
It's weird, whenever I do that, I just get the tweet in like a new column on the right, no different URL. It may be because I am viewing on mobile version, but other than that, idk.
