Ducklings feet are red... Should this be a concern?

[brooder]

Hello, I am new to raising ducks or any other kind of poultry, and I just noticed that my eleven day old ducklings' feet have turned red and you can see the their veins. I am concerned about a bacterial infection, and I would appreciate help that anyone could give me. I will attach some pictures:

Thank you, but I'm still concerned. Why would the coloration suddenly change? I am not very educated on the subject, so I may be worrying about nothing...

Yeah....Your worried about nothing....They have lots of blood vessels in their feet.... Veins too...Just ignore it...
