Any guesses on this Maran/Ameraucana chick? It was suppose to be an Olive Egger, but it has a single comb. Found out it is a

7/8 Maran and 1/8 Ameraucana. It is about 5 1/2 weeks old. I also noticed black spots on its comb. Is that normal? Also has some wattle already developing. More feathers on its legs than head! haha.. Also very slow feathering on shoulders, head and neck. The breeder I got her from has a really high success rate on sexing and we all thought this was a pullet, but now am beginning to wonder. So roo or pullet?
And by the way, when I look for earlobes, all I see is fur. Do they have to be a certain age to see earlobes?
