Jim,
I wanted to let you know that a correction needs to be made in your statement that copper is toxic to sheep and goats. I own dairy goats on our homestead. Copper is indeed toxic to sheep, BUT COPPER IS CRITICAL FOR THE GOOD HEALTH OF GOATS. In fact copper sulfate is given as a supplement at times, especially with the darker goats to keep them from turning chocolate brown instead of the black coat color they should have. The belief that copper is toxic to goats is a common misconception and I have had nearly knock down drag-down fights with different feed store employees who didn’t want to sell me the copper salt blocks when they knew I had goats. See David Mackenzie’s excellent “Goat Husbandry” for more information, or “Natural Goat Care” by Pat Coleby. Both available from Amazon.com. – Midwest Farm Mom
JWR’s Reply: I defer to to your experience and study on the subject. I have corrected my original post. Many Thanks!
