Hi!!!!! I have two almost 4 week old partridge wyandotte chicks and they look VERY different as they are aging! I’m questioning if the breed is even correct or if one is just a rooster! Help please 
Chick one has district color changes form head and stomach and is much fluffier and has tan feet and legs.
Chick two has dark legs, fluffy on the top of its head and beak Looks different.
