I have read they are fine, I am new too but would feed these as well as pig's neck. I would love to know what they look like. I'm having a hard time imagining that they have much meat. My local butcher will not sell them though, he has some rules with mad cow that dictate he cannot. I guess anything that touches the brain - so the neck spinal cord - is off limits for sale where I am. According to this one person...So even though I know the cow as grass fed and fine, he cannot release those parts. Post more if you try 'em.
