I live in Nebraska...so if that tells you anything...I have access to feedmills, grain bins, farmers, etc. Is there any ONE grain I could just go buy a ton of and be comfortable knowing they had what they needed? They do not free range often. We have multiple predators around. I could supplement with table scraps etc. but i just always see people on here with feed recipes saying a pound of this two pounds of that half a pouind of this a pound of these five things four pounds of that one pound of this. Too much crap to think about. Can't there be a more simple way?? I dont want store bought commercial feeds. Too much clumping and moisture issues. I also use DE ...FYI Can I buy a ton of rolled oats and call it good? A ton of BOSS? Corn? Thanks!
