I bought a 50# bag a few weeks ago and haven't opened it yet. I still have some small baggies I ordered online still. But I was wondering once you open it how do you guys store such a large amount. The humidity is bad here and I have it currently down at the horse stall. But want to bring it up to my carport to use it at the chicken coop. So do you guys just leave it in the original bag or store it in another container? Has anyone had trouble storing it or problems with humidity or moisture?
