Any special salt needed for licks?
I'm getting ready to set up salt licks around my property. I'm planning to buy 50-pound bags of salt from my local Tractor Supply. They stock an assortment of salt and mineral mixes - the most expensive one has several trace minerals and is about twice as expensive as plain salt. Is there any reason that I should spend the extra money for the more expensive salt? Thanks for any light that you can shed on this. - CB
