blue earlobes

I just accuired a couple of chickens last week that are about 13 weeks old. I was told that they are olive eggers but I don’t know much else about them or their parents. I have noticed that one of them has very pretty blue earlobes. Do y’all think her eggs will be blue?

Is this normal

Hello all, I have 4, 5 week old silkies from an extremely good breeder (Kate Morreale) bought as hatching eggs. As of now they do not have blue ear lobes at all-- They are just the color of the bird's skin. And yes, I am positive I am looking in the right place. I somehow cannot remember at all...
