It is hard to make decisions like you are doing = I should be doing it also. I have 20 Nigerian does, 2 bucks and we have a few sheep and chickens. Getting too old for all the work but try hard to keep up. Do you have a vet that would work with you and help you some. I have a wonderful vet clinic that has helped me with so many things over the years. Did you get fecals done? Personally - I tried the organic solutions for awhile but never helped me any. Also bought a ram lamb from a lady that used the organic ways and the company you previously mentioned. It was so overloaded with parasites and even with several times the vet trying we lost him. Depending on where we live may affect the parasite problem. Good luck with your decision.
