Hello Nevada, Pecked is if you have a hammer in one hand and a round tip in the other hand, I would look at the outline and see if it has a feature of something, and pick out the different size pecked holes ? and use a piece of white chalk with a sharp end to just mark the bottom of the small hole, if there's difference sizes I would mark them with different colors and see if anything appears, look for arrows, letters, and numbers, profile. Watch a chicken they will show you how to do it ( just kiddin )
