It's possible she had a breast blister that opened and now it is extremely infected.

this happens fast within 72 hrs another has it above tail feathers. Clear eyes nice combs still laying and eating and in good spirits. Any ideas?

Has that black spot always been on her leg?

One is on the "tummy" and one is above the tail feathers, according to the OP. If the one is on the breast area near the crop, it could be a breast blister that has become abscessed, but that almost looks like a tumor. Do your chickens have other symptoms such as sitting a lot of the time, or not roosting, but laying on the floor of the coop?

Looks like a tumor to me.

Did she die, or is she still alive? Is it worse or better?
