Hen with Pale face and wattle and comb. What do I do ?

I have noticed since 9/6/13 I let a day pass hoping when she slept she would get rid of what she has. There was a lot of heat the week before or she hasn't been eating. Shes not infested with any lice or mites. She isn't molting either and she laid an egg yesterday. She is a old English bantam and young and is taking care of a the only cockerel that came from her clutch of 4 eggs. The cockerel is barely competing 3 months he was born in June ,near after my birthday, but he doesn't show any behaviors his mom has.

Is she old enough to be going broody? Mine does even without eggs. Everything goes pale
