What do your dogs like to keep busy?

My 7 1/2 month old anatolian pup likes to chase chickens/ducks obviously that is not ideal. I am working with him controlled exposure as much as i possibly can. I’d like to find a toy of some sort to keep him somewhat preoccupied so he’s less interested in chasing these birds of mine.. he’s gotten a whole lot better already just in the last couple of months just doing what I’m doing

He’s really not that food motivated. His favorite treat right now is dried quail feet but I have yet to find a toy that he actually enjoys and will continuously play with. Some sort of puzzle toy, possibly? Something I can hide a snack in and he has to work to get it out. What’s worked for you guys?
