Agree with amiga. Do you have a side pic?
The light one makes me thing pekin, but if I am seeing right there is a shaded mask on that one which would likely make it a fawn and white runner.
The yellow one is either a buff or maybe a runner, a pic with better light and it standing alone would be helpful in figuring it out. It appears to have a light mask which makes me think buff, but would need a better pic to see the mask and how it stands.
The other is a mallard. A rouen would be bigger and have a second solid eye stripe
