We have one very similar. He's the old rooster - the young blood challenged him and won, leaving the old boy blind in both eyes and with a tatty comb but it's been a few months now and he is still managing to get around and feed himself but he prefers to sit still all day and move about at night. He's currently grandfathering three orphan chicks whose mothers were taken by a dog. I'm not sure if he knows he's looking after them but the chicks hang with him all day.
We feed him on a plastic tray so he can hear when his feet are on the food and he starts pecking.
As for helping him on his way, we pull their necks and then chop their heads off.
The neck pull kills them but the twitching and flapping might make you think they're not dead so a quick chop with a machete confirms it.
If you can figure out what the seizures are being caused by and can remedy them, blindness doesn't seem to that much of a problem for them.
Is it the black one in your avatar? He looks lovely. We don't have any blacks, only black tail whites, black tail buffs and a couple of blue females (I think they are blues anyway).
