Salt in chicken water?

Meg, Can salt be added to chicken water to give a few degrees of freeze protection? I have read both that it is toxic and that it can be fed free choice. Some feeds include 0.15 to 0.25%. Should we try it and if so what ratio?

MEG: FOR BEST HEALTH, CHICKENS REQUIRE A WATER SALINITY UNDER 2000 MG/L (=PPM), BUT CAN TOLERATE TWICE THAT FOR LIMITED PERIODS.
