Handle them. 

Lift them up and talk to them. 

Hand feed them. 

As others have said feed them at set times with the last feed being in their run.

I have 6 Shetlands now but had a Swedish blue drake, his KC wife, and their three daughters that were all killed by a fox even though they hadn't had their wings clipped.  None of them can fly very far.  Just a quick flutter up and down.  They were in my front paddock but too accessible to other animals (including rabbit and deer ringbarking my fruit trees  ); so my Shetlands and chooks are in the back yard where it's a bit more secure.

I feed them outside when I let them out and again in the afternoon, mainly because my lead duck quacks like an old witch 

They live happily with 5 rescue hens and an old white hen, in about a third of an acre of weedy, grassy ground with a big pond and leyland trees, with an outside run and inside run for each breed - the hens come into their own run at dusk, the ducks come in to theirs when I go to shut the popholes because they know they'll get a little more feed and a wee bedtime chat 

They don't call me the bird lady here for nothing
