Please help, chicken has black scabs or something

[Rosieschickens]

What is my chicken suffering from, and how can I help her? She has stopped laying eggs for about a week now. She seems normal in the way she acts but i know she is sick. As you can see in the pictures she has what looks to be scabs. She had white and black spots in her comb.

It looks like dry fowl pox to me, a virus that will run its course in about 3-4 weeks.

Add some poultry vitamins to her water and feel her crop in the evening to see if she eats enough.
You can also feed her some scrambled eggs to provide some animal protein.

Oh, and no need to separate her as the virus will be transmitted mostly by mosquitos.
