I have a half blind Odin too! Mine is an older gentleman I got when he was around 2 retired from a small scale breeder. He had been in a fight with an up and comer cockerel and lost a good portion of his sight in the eye. Luckily he is still great at watching over the ladies. He has lots of room now and much less competition.I have my hen "Odin". Odin is a buff orphington, and she was left half blind by a rooster (we ate him).
I spent a full month hand feeding her several times a day and guarding her from the rest of the flock until she got a handle on eating.
She is my favorite girl, and is happy and healthy three years later, as long as I always throw the treats to her left
(Ps. Just kidding, she still gets handfed her treats.)
