unspecified clump of meet in bag of chicken

Hi a few months ago I bought Tyson buffalo chicken wings. After I dumped some on the cooking sheet I noticed a big Ole clump of something but at that point I thought it was wings stuck together. I started cooking n went to turn over wings and the clump ended up being a massive pile of yukky stuff. Almost looked like ground up parts from a machine grounding up chicken or something. I took it off and put to the side and was disgusted I was going to call Tyson chicken. I proceeded to call them that day but closed for conferences or something like that what I can remember. So I wrapped in aluminum foil then put into a zip lock bag. As I took it out of refrigerator last week I went to look at it n since then it dried up like a rock and started EATING THROUGH the aluminum foil. Literally! !!! Almost like what acid would do when you apply to a material. Now I'm wondering what the heck is in that made aluminum foil do that. And it's good foil too.
