What is this on my butchered chicken?

[TJAnonymous]

We butchered 7 roosters last night. One of them had these small, beige/yellowish granules all over in the clear goo covering his muscles. It was all over the legs and breast... But not in the actual muscle meat itself. Just the clear covering. Has anyone ever seen this before? It does wash off if you clear the goo. None of the other birds had this, btw... And they were all penned together.

I don’t butcher, so I have never seen that. Hopefully others will offer help.

I don't butcher, either, but those look like fat deposits.

Clear goo is fasica or connective tissue. I haven't noticed the yellow granulars, but mine have lots of fat in the same spots. I think that's the beginning of fat

Most of my pictures are of plucked but I think there's a small spot lower right.
