If I ever go the way of water dosing, I plan to fry my brain doing the math to try to determine how much medication needs to go in in relation to both the overall water volume, as well as how much each bird drinks per day. I assume that the issue of body weight would not be as crucial since intake of water should hopefully scale somewhat linearly with body weight.... So the real unknown would be average consumption of water per bird per day. No matter what, would entail using a lot more meds than just syringing it directly into them undiluted.
