Ok. I hate to :deadhorse: , but I have a couple questions for those of you that use it. Mainly, which kind do you use, and how do you feed it? And how does it handle wet weather? Looking at all of the different formulas and the recommendations, we would probably need the 8/s, but it says feed 4 oz/hd/day, instead of free choice? Couldn't we just feed it free choice??? The 10 says free choice, but without salt wouldn't they just fly through it? :help:
