How to pick up ducks?

I have two beautiful runner ducks, but unfortunately they don't want to be caught or picked up. I had a Muscovy duck briefly and it would keep walking behind me and not fear me. These 2 are different, they run to me when i get home or give them food, but not closer that 2 meters. For every step closer they will walk away...

Is there a way to get them used to me? If I sit down for a bit they will come and sit down chill right with me.
