I agree that chickens need animal protein (bugs, etc...) but be careful buying food with meat & bone meal or other non-specific protein sources (animal digest, animal fat, etc..) These are know to be from rendered animals (often 4d) or containing traces of pentobarbitol as well as other chemicals. Even the FDA will say so ==>

I think fish meal would be ideal but all fish meal is treated with ethoxyquin in the USA and if it is shipped in from china then it was probably fed some kind of toxic cr@p too.
I wonder if I can grow my own fish??- LOL. I have about 10 feeder gold fish in the stock tank right now, hmm.....
DMRippy- you should check with the local farmers markets & such. I get boxes of bruised greens/tomatoes for free that they are just going to throw away. My guys LOVE tomatoes & grapes the best, & apples.
