I used to find maize was more useful than aniseed. Hand feeding cut maize onto rides didn't necessarily stop them wandering, but it meant they always came back for it. Mixing maize into feed however, i found that they just pulled out the wheat to get the maize!
If you do carry on using aniseed, dilute it with cheap vegetable oil before you mix it, it helps get a better coverage, and its another attractant. Realistically you don't need very much aniseed at all.
Another thing you can use instead of aniseed is curry powder. Works similarly to aniseed, but you smell like the local takeaway instead.
If you don't try, you won't know!
Good Luck!
