I have two White Layer ducks and the smaller (I am assuming runt since he still is not fully feathered compared to the other duck who feathered about 2 weeks ago) has these red feet. I am not sure if they are broken blood vessels, too cold, or something else. Google hasn't given en any answers so I wanted to ask here. He isnt struggling to run, walk, or forage. No signs of limpness so I wonder if there is anything i should do? This duck seems to get every problem imaginable.
