I told a friend of mine with chickens that parrots love beak rubs. And I would bet chickens do too.

Next time I saw him be told me his buddies were calling him the chicken whisperer cause now all the chickens come up to him for beak rubs.

Give that a try with yours and see if it helps build trust.

Chickens are pretty cool too. Honestly I have a soft spot for most birds.
