A pesky fox (I suspect) snatched one of my lovely pekins two nights ago after two years of no incidents . I decided to move my remaining duck (I am picking up a new mate for him today I hope that works out!) to my little goat pasture. It's a 125 ft x 50 ft enclosure with four pygmies. They all get along fine but I am wondering if the loose minerals that the goats get could possibly harm my ducks? Isn't copper toxic to them? Let me know what you think!
