The chicken in the sausage (if that is the meat source) would be fine I'm sure, but its what else they fill it with that I'd want to find out about. Have you an ingredience list?
See, the other issue with sausages in particular, is you don't know from where abouts the meat comes from. You may be thinking, "Oh I don't care" but seriously, mashed up chickens feet? powdered chickens beak? -Not saying all sausages are like this but there are some out there and its often hard to tell the good from the bad.
