Have you done this yourself?Fill a water bottle with super salty water. Like 1/4th salt and close it up tight and toss it in the water dish. It will keep it from freezing as fast

What temperatures have you used it at, how big is your waterer, how big is the salt water bottle, how much time does it buy, have you compared it side by side?Yeah it’s not great but buys you some time. If it’s cold enough the bottle will get froze in the block eventually
Sure.No it’s a tub of chicken water not a science fair experiment
So, salt lowers the freezing point of water. Water without salt that normally freezes at 32F can freeze at 0F if you add enough salt. However, that doesn't change the temperature of the water, just the temperature at which freezing starts. It doesn't keep the water warmer, just delays the onset of freezing. However, salt also decreases the specific heat of water, so it helps the water in the bottle retain more heat from the sun or another source. A bottle of saltwater will obtain a higher temperature compared to a bottle of freshwater for the same amount of sun exposure (this may be just a few degrees difference).Sure.
Before I depend on this for my chickens, I want to try it next to a similar bucket without the salt water. It would save me a lot of time and effort if you could give some ballpark figures of what you've done.
I've seen a couple side by side comparisons on you tube where they concluded there was no difference. They didn't try many variations, though, and were not very specific in how long it took to freeze - they just left it overnight one night to see if the salt bottle would keep the waterer from freezing at all.
They didn't see if it a difference if it is near the freeze point or many degrees below freezing. Or different ratios of salt water bottle to bucket size, or open/closed top.
