LauraLee...a coffee grinder will do it. I have one I bought for like $15 just to grind pellets and even the larger crumble for my bantam chicks whenever needed.
LauraLee...how far from Lexington are you? If Lex is too far, call around your area and ask who carries "Hallway layer pellets". Hallway mills their own and they are mini pellets, that is what I feed my bantams, even my tiny OEGBs. In Lex, Farmer's Feed Mill mills for Hallway and they are on W. Louden...exit 115 off I-75
This link is their "find location" link...just select Kentucky and a list of suppliers that carry it will come up for you

Or if you want a little mille boy from Cyn's, when I get back with them you could come up and get him and I could pick up 100 lbs or so for you ahead of time and you could get it at the same time
I am just 2.5 hours north of you up I-75. LOL Little roo would be free of charge, just pay for the food. What a deal!
