what kind of ducks do I have

[silkiecuddles]

The yellow one definitely looks like an Indian runner to me :/

I have fawn runners, black runners, Pekins, and I've had other breeds in the past. I've never seen that pale of a bill.

I did see it once, but it wasn't a healthy baby.
His owner fed him cookies and crisps.
It is possible, but if he's completely healthy I guess not.
Sorry, wish I could help you figure it out

Only other image I have until tomorrow they've been put to bed.
