It never occurred to me that this chick might be a roo. What do you think?

5.5 week old, not 100% sure of the breed as it was supposed to be a lavender Orpington but more likely an olive egger or mix of breeds. Just took her(?) to the vet because she was having trouble walking & the vet said growing pains (hence the x-ray). She(?) also in the past few days developed a larger and slightly redder comb than the others.

The comb size and color on such a young bird says cockerel to me.

I agree, that looks like a cockerel.
