can you hear me now? :
Looks to me the person above my first post knows something about what it could be as well. He may be right and I may be wrong because I am only taking my educated guess.
I am a gigantic guesser not an educated one I destroyed a bile duct this weekend processing a bird...
If I had to take a guess they cut the bile duct when it was being processed. (Ask me how I learned about that - ) If that's the case then good she threw it away and probably the rest of the chicken too.
