There are a few ways to get vitamins in goosebaby is right took me a few times but the syringe is the best . And Iv done it without help. You can do it. I also sprout grains for my geese and feed on day 3 of sprouting the evening before I add all there suplements to the sprouts. Water with geese is also a play toy and grooming tool so you never know how much they got. Another trick is whole wheat in about a inch of water they love getting the wheat from the bottom of the pan and do digest some of the water.Is that all stuff that goes in the water? I can't get her to take anything from my hand. She didn't even want the comfrey leaf but she ate it when I broke it up and let it float on the water.
