I have some Auromycin crumbles left over from last year's abortion storm (never used it, the abortions had stopped). As far as dosing, I assume I just count the number of heads of goats in the pen and alot for that many. The Crumbles have been in the freezer section of an upright fridge that I store feed in. It sits under a pole barn. We don't get above 90 around here in the summer, but it can be humid. I haven't opened them up. What is the likelihood they are any good at this point? Would it be smarter to feed this until I can get to the mill and buy a new bag? I realize a number of these questions could be answered on the bag, but it is down at the goat pen and it is barely above freezing right now outisde. I'd rather go down prepared beforehand. Thanks!
