Yes, the bulging eye is more concerning than just a blind chicken. It could easily rupture leading to nasty infections or other health problems. Possibly long term. In other words, long term special care and maintenance is more than likely this chicks future. Not to mention the underlying that you can't physically see. The odd head shape can indicate mental retardation and other brain deformities that are beyond eye problems. The constant cherping and not eating/drinking could be fear and confuion, or it could be pain and, well, the alternative i mentioned. Me personally, i would atleast do what i could, but in the back of my mind i know culling would be best for it. Because of my own, i won't recommend anything, but like i said before, if you chose to cull it, noone would balme you a bit.
