UPDATE: He got well for about a month and just last week I noticed a decline in his health again. He is horribly unbalanced (regularly doing the splits) and basically "chicken crawling" on just his upper legs to get around while using his wings, he's so active and devours food still and drinks lots of electrolyte water. I've been giving him half a B complex vitamin a day with fresh "save a chick" electrolyte water. I plan on getting some poultry cell tomorrow, or a baby probiotic as well as some yogurt. He got better so much faster last time so I'm starting to worry and wonder why he is sick once again with the same symptoms? Any Insite will be greatly appreciated!
Notes:
-full crop at night, empty in morning
-NO eye or nose discharge/puffy face or eyes
-Normal poo
-Bright red comb and still tries to preen
-Does NOT forage, as he has a crossed beak and doesn't care to (gets chopped veggies
though)
-Doesn't like eggs, so that's not an option to feed him
-Has function of feet/legs, NOT paralyzed, he scoots around (angerly)

I currently have him in a sling so he's not constantly flailing about, he's so active! I also gave him his first Does of Vet RX, hoping that helps, but too soon to tell.
Like i said before, he's not droopy and looking like he's given up, so active, talkative, eats so much and drinks a healthy serving of water every day. The only thing that seems to be wrong with his is his ability to stand and walk.
