We received a Royal Palm turkey poult last year that had one eye partly open, by the time she was 2 weeks old she kept it closed most of the time. She had a film over it, still does. We rarely see it open.
She was and still is uncoordinated. We have trained her with two long bamboo poles that we use on either side of her when she is out in the run and it is time to go into the coop. We try to bring her in while it is still light out as she shrinks away from dark doorways.
The other turkey poults were curious about her closed eye but did not pick at her eye to the point of injury.
She slept on the floor when we moved her to the coop, but learned to fly up to the lowest roost after a few weeks. Several times she has flown up to the peak of the barn. At first she was afraid to fly down, so DH had to get his 100ft ladder out to get her down. (They are best buddies.)
Now she flies down on her own.
She was the last of the batch to start laying and since we don't know if her blindness is genetic or a birth injury we do not incubate her eggs, we do enjoy eating them.
She flies over the turkey run fence, gets lost and starts roaming our lot looking for DH. She uses sound as a way to tell where she is and always has her head turned to see from her good eye.
DH has discovered that he loves turkeys the best and she has become his pet.
Good luck with your turkey.
