Is this a tumour? Graphic photos!

Sorry for the graphic photos.
This was right at the bottom of the gizzard and seemed to be blocking any food/water from getting into the small intestine? Her gizzard was full of stones and food, she was drinking quite a bit of water but she was very dehydrated when I did the autopsy.

More of the story here
"Sick chicken, intestinal blockage?"

I am going to tag @casportpony to see if she knows if that is a tumor possibly.
