@Amiga Thank you so much for reading this! it is long. I want to take him to a vet, but I'm fearful they won't hear me out.
He's eating dog kibble, I know that is horrible, but he and his brother have been eating it for 3 years. 24% protein. They were also sharing a bit of cheese in the morning. and he eats Spring Mix salad and minnows. Plus whatever they forage.
Here is all of the things I notice
If he tries to scratch his head with his foot, he wobbles a bit. He loses his balance coming up the stairs and has fallen over. The weird thing is he refuses to use his wings for balance.
He LOVES his water bowl, runs to it first thing in the am and sits by it drinking.
He used to run around with the dog and now, makes little effort to do that, so it makes me think his legs hurt.
He has a slight limp, but after eating a bunch of greens last night, he looked good today.
VERY water poop, I've looked at it, it's clear with bits of green grass (looks like parsley). But again, he drinks a lot of water.
Currently (it's 4pm here) he's swimming in the lake with his brother. they will usually come up and forage in the lawn and then come upstairs.
He gets tired easily and will sit down to forage.
I'm going to try Brewers Yeast tomorrow and then set up an appointment if that doesn't work.
This has been going on for about 6 weeks, but I'm now really paying attention to him.
