I'm wondering what the optimum pH of water should be for optimum health? Are chickens like humans, and prefer a higher pH for optimum health? I have the ability to monitor my water source and can make any adjustments needed. My water source is very clean. Its rainwater that has been triple filtered and UV treated. Comes out 10 PPM and 5.2 pH at the spigot. I'm thinking of mixing up some mineral water using Azomite. Is this a good idea or should I stick to putting it in the pellets?
