Tadpole and KJ, I'm assuming the CX are "looking pretty bad" either due to heart or leg issues. At least, these two problems are very common with this breed. If it is either of these problems, they are okay to eat.
If it is an illness like cocci, then I dunno. I would probably dispose of a diseased bird, if it weren't heart or leg issues.
