Rooster with eye goop

[Jillirene]

This rooster has been down for about 2 weeks. I tried treating him for a vitamin deficiency and I've given antibiotics incase of an infection. He can't balance but he can kick both legs and flap his tail. He'll move his feet like he's walking if I hold him up by his breast. I was planning to put him down, and then today I noticed his goop on his eye. He's eating, drinking and eliminating. Any suggestions on what to do, or should I just dispatch him?

How old is he? Was he vaccinated for Mareks disease? Are either of his toes curled under?" Have you added any new birds recenrly?

About 1 year old. Not vaccinated. Yes, he does seem to have his toes curled sometimes. I added a couple of Guineas over 2 months ago.
