Sick bird

Rubba Johanna

I just checked my bird seed on my patio floor and I'm seeing what looks like a House Finch chick (an adult male was feeding it) with growths on its face. Reddish bumps are on either side of the beak and on the forehead right above the eye. There's a dark grey patch behind the forehead bump, on the bird's cap. The bird seems unable to close its beak. I can eat, drink, and fly. Does anybody know what this might be? I'll try and get a photo.
