So, I don't know biology, other than the basics, but this sounds more like, possibly, an equilibrium/homeostasis thing, no? If the chick gets the full 'dose' but too much total water intake, maybe the equilibrium state in the cells doesn't reach a high enough level to kill the coccidia? Whereas the same dose with less fluid intake creates a strong 'push' force towards homeostasis?? So more of the actual treatment (or higher concertation of it) actually gets into the cells??
Does this sound reasonable, or am I going in the wrong direction trying to understand why concentration and absolute dosage are different in this case.
