As i was giving one of my birds a shot, a question popped into my head. how do you give vitamins to a large amount of birds if you are medicating the water. I've herd not to mix Meds & Vitamins, so how do you give them both with out putting both in the water? If I use two seperate bowls, surely they will just drink the Vit water.Does anyplace sell Vit. you can put in feed, but sell it in tubs, not those small little packets that you have to buy a lot of.
