Elderly chickens

[taprock]

I am wondering how others handle elderly chickens. My chickens are for eggs primarily, but are also pets and everyone’s named. Currently I have three elderly roosters from ages 4 to 8. They are wonderful roosters. They have grown extremely thin bordering on emaciated even though they are fed well. Two have lost sight in one eye. One has been in the house since Christmas after the goose grabbed him. I’m fighting with the decision to try and save them, or to euthanize them.
Has anyone ever had success with having an elderly bird gain weight and recover health?

Mine are treated regularly, maybe babied a little bit. I certainly wouldn't consider 4 to be elderly though.

Keep their dish filled with food, make it a mash if you must so that they eat. Are they alone or aren't they together?

They shouldn't be losing weight unless there is an underlying illness.
Have you tried worming them? You could take a fecal sample to a vet to see if they need worming.
Have you checked for lice and mites recently?
Are they having any other issues - trouble walking, behavioral problems, being bullied?
Do your other chickens seem healthy?
They could also have a more serious illness such as cancer or kidney disease. I would try to eliminate all other causes before considering those. If you do suspect a more serious illness, you could euthanize the one who seems to be doing the worst and have someone (either you, a friend or a vet) do an autopsy to confirm.
Hoping the answer is simple Our chickens are egg providing pets as well.
