i contacted the company via their web site and the rep told me that by mixing it may not give the full benefits of using it ..they did send me directions to a place that sells the larger bags and i will be calling them today to check prices out ..i already buy my straw from the place they sent me ..oh and they sent me a coupon for 2 dollars off ..i wish i had a printer now ..lolCan I mixed this feather fixer in with their normal feed?
