Botulism would be about the only thing drinking that tainted water might cause. Here is a link: http://www.thepoultrysite.com/diseaseinfo/19/botulismWe've been treating them all with 1.5 tsp to a gallon. I'm not sure, but if it is cocci wouldn't they all have the same strain? They all seemed to come down with it at the same time.
On another note, we've had them in one section of our garage/barn while we're finishing their actual coop, so I've been searching around to see if there's something they may have gotten into. Didn't find much except one thing that may or may not be significant. It's a bit nasty, but i keep a 2 or so gallon bucket partially filled with water as a mouse trap. Mice climb on the rim and more often than not fall in and that's the end of them. Well there were definitely several decomposing mice at the bottom and a lot of the water was missing. Even though it was in a section they typically never went to, I'm almost positive they must have drank some of the water (droppings around it). I have no idea what if any impact this would have on them, but I would guess they could get e-coli or some other bacterial infection (probably among other things). Don't know if this would change anyone's thought's, but maybe this caused similar symptoms to cocci, I have no clue. The rooster seems to get bursts of energy, where you'd almost think he was back to normal, but then he goes right back to being lethargic and seemingly very sleepy. I gave him some crumble mash mixed with the corid water and he was eating that up good. If anyone's had a similar experience with their chicken's drinking putrid water, please let me know what if any impact that had. Like I mentioned previously though, the hens bounced back pretty quickly after giving the Corid treatment. Sorry to keep this going so long, but at the same time that's what make's a thread of this kind useful for people in the future. I've seen so many that ask a question or two, a bunch of people reply and then nothing. It's nice to know the end result of issue/suggestions for future reference (at least I think so). Have a good night all.
