Sinus canker

What do I need to do?

You should do as @Eggcessive recommended and try to remove the pus.

I just dealt with this with my 9 yr old Light Brahma hen. I sprayed saline solution on it, let it soak for just a few mins and squeezed from the comb forward and it popped out like a plug. Cleaned out both nostrils.
