Ah...but you aren't having constant, smelly, liquid diarrhea either, are you? If you were, your doctor would be recommending electrolyte replacement and probiotics in the form of yogurt, cottage cheese, etc.
Ordinarily I would agree..and with any other kind of chicken I would.
But we are talking about CX, who have frequent diarrhea stools...one only has to look at the yellow, frothy consistency and smell the horrible smell to know these birds are constantly losing fluid and their bowels are stripped of good flora.
Anyone who has had diarrhea for just a few days knows how it depletes the electrolytes, weakens them and everything they eat just passes through them in a liquid stream. Whenever you are having liquid stools, you are losing more than just the liquid.
Ever wonder why these birds drink constantly? They are attempting to rehydrate but all the water they drink will not replenish the electrolytes lost in their constant diarrhea.
All the high pro, vitamin laced feed in the world doesn't help if it shoots straight through the animal and comes out onto the ground...ever wonder why so many people feeding their high pro feeds report high mortality in their CX? Guess the vitamins in the feed didn't quite stop those heart attacks...
One solution is to culture their bowels from the first day by giving UP/ACV in the water or fermented foods, thus restoring good bowel flora and function, allowing these birds to retain their nutrition and their liquid. Best solution.
If you aren't doing that, vitamins in the water is at least better than nothing at all. Maybe some of them will actually be absorbed before they come out the backside.
