Does she have poor circulation?

[Nats Chickens]

It is not uncommon for a large combed hen or rooster to have some darkening especially on the tips or back of the comb. Is she a white leghorn? I have heard of some hens crowing.

No. She crows, but she lays eggs and doesn't mount the others or anything.
