What in the world in this thing I found in one of the chickens I just slaughtered? My first thought upon finding it was TUMOR! Then I cut it in half and now I'm much more confused!! The thing is is has what looks like a hard boiled egg yolk with a thin layer of cooked egg white wrapped around it, encased inside a multi layered tissue thing. This mass was inside the canal that the eggs are in. There are a bunch of other little things in it too. Can anyone help??
