Welcome to Consolidated Kansas Ron Rose. To answer your questions, the way I find the thread is to click on where it says "new posts" and that will open up a drop down and then I click on "where I've posted". That will bring up a list of threads where you have ever posted and it will show you whether there are any new replies on that thread as well.
Regarding keeping the water cool, I don't even try. Back when I had just a handful of birds I did as you are doing: froze gallon water containers and put one in each afternoon around 1pm. However now that I have about a hundred birds, it isn't cost effective to keep freezing water, just to have it become really warm before I put it back in the freezer. The birds really don't seem to care - the main thing is that they have water available. I keep several waterers in different areas of my chicken yard so there is always one that is in shade. That probably doesn't change the temperature of the water itself that much, but it does mean they don't have to stand in the sun while they're drinking.
You probably do have a couple of roosters more than you need. Butchering isn't fun but after you've done a few you realize it isn't that bad either. With the numbers you have, it is inevitable you will end up with more, as hens will go broody and hatch out chicks and….some of them will be roosters.
