Here are some pics of a wyandotte I've had for some years now. She has an extremely large crown and wattles with mottled grey/blue feathering. I'm pretty sure she's been crossed with some other breed but I'm just not sure. She lays pale, white eggs.
Need a better picture of the bird to tell what it might be but as of now I will say that it is not a Wyandotte.
Wyandottes have Red ear lobes not White.
