I realized that Phoebe, my sweet Goose is actually Blind.
I had thought/worried that she'd become (well) feeble. I couldn't figure it out. I mean that she is only ten years old and was stumbling while walking, getting stuck in wooded areas/uneven ground, walking into walls-fencing-trees.
At first she spent all of the time in the COOP (right after she hatched/brooded little Drew, her Adopted-Duck-son). She would only occasionally came out to join the flock but when I called the flock back to the COOP at night, she would just linger behind (not follow the other birds).
Night after night, I ended up having to fetch her back to the COOP. Finally I stuck her in the first year restricted side-pen, so she doesn't wander and get lost. I then noticed that she stayed in the corner away from the ducklings - jumping at their quacks but not flinching when they ran towards her (well until they bumped into her).
Went in and waived my hand/wiggled my fingers in front of her, realizing that she didn't even flinch. Also that she hadn't been eating, so I put her beak into the food bowl and immediately she started to devour the feed. Going to have to start hand feeding her. I think she must have started to go gradually blind.
Does anyone know what might have happened? Anyone with experience with a blind bird? Anything I can do?
