By now you have probably found that copper sulfate can be used to treat fowlpox in chickens and used as an additive to feed to prevent fowlpox. Some believe a deficiency of copper is a reason birds are susceptible to fowlpox. Pat Colby suggests, for poultry, adding a minute amount of copper into the diet. For one bird, the infected bird, mix ⅟₃₂ of a teaspoon (a minute pinch) of copper sulphate into a mash of bran and molasses or honey. As a preventative for the flock add ⅛ of a teaspoon for a flock of 6 to 10 birds, daily in their feed. Copper sulfate should be administered for 5-7 days at a time, with a break of at least 14 days between treatments. Garlic and or vitamin C in the drinking water will ensure that sick birds do not get any secondary infection. A drop of eucalyptus oil (internally) daily is also helpful.
