I have been using Avia Charge-2000 and Immuno Charge with great success on my chickens, ducks, and geese. When I went to reorder from Murray McMurray, I found that they no longer carried these products. I did some checking and found that the owner has his own website now and is no longer wholesaling. What a relief! I know many other duck and waterfowl owners were worried about finding these products. These products can be found on www.innovatorsllc.net. I just wanted to let all my friends know.
