I have no idea what I just found, but it looks pretty awful and I'm afraid to eat the meat. I just spatchcock a chicken and when drying the bird off, I found a lump under the skin. I started to ignore it, but got curious, so cut a small slit in the skin. There was a dense, hard black mass surrounded by very yellow, dry fat and it looked like some sort of tumor. It pulled free easily, but honestly grossed me out, and I'm not very weak stomached. Anyone else ever found something like this?
