[Jacob-list] Shearing Time! / Grey Banding in Fleeces

[Linda]

This is an interesting topic. Most of the information online does relate to Juliet's area of the world.  I wasn't able to find much about the states. 
What are the possibilities of getting too much copper with the boluses? 
I don't know about molybdenum here, but our soils are high in iron. I don't see the banding every year and only in a few animals. Would some animals require more copper than others? Would a copper problem account for overall early graying?
