Giving copper bolus this evening and the bolus is the 4gram. Only giving to adults goats (grown). I tried he pitted prunes and it was somewhat a success. My usual hogs wanted all of them while 4 did not. One goat that had already had one grabbed off the ground one prune with a 4 gram bolus in it making her 8 grams of copper. Problem is I have 3 that look a like and not sure with all the commotion going on, which one it was. Is any thing at this point I can do?
