I am treating my chickens with Corid, after finding a pile with some bloody poop. I have no idea who it was, but it doesn't matter, they're all being treated. I was actually fully expecting to dump the water out each day, rinse the pan, and then refill it with fresh water and a new dose of Corid as well. But as luck would have it... the temperatures dropped and the water froze. I didn't have another dish of water for them (I know it has to be their only drinking source), and the garden hose was ALSO frozen (this is Georgia, it rarely freezes here). So knowing only the surface was frozen, I took a sledge hammer and busted the ice up so they could actually access the WATER. Since I can't refill it yet, I didn't replace it, even after breaking up the ice. I just let them have the existing water. My question is, are they technically still getting dosed with Corid enough to count it as another day of treatment? The water that froze over, was water that I had added Corid to and it was still at normal strength, not "clean" water, or diluted with more water. However, it is actually clean as they haven't made the water or ice dirty, so I'm not THAT worried about changing it. Since I can't replace it though, thanks to the frozen garden hose, I'm not sure if I should consider them to be on day 2 and 3 of their treatment, or still on day 1. Since no water has been added at all, they are still getting the full dose strength when they drink from it. Should I continue counting the days, or wait until I can replace the water properly, and consider that to be Day 2?
