Turkey Staggering

[Pnvhorses]

Bought a @2yo tom a few weeks ago. Three days ago, he started staggering -- uneven gait, falling to right, walking in circles instead of straight line.
Eating/drinking fine, but poop really runny.
What's going on??

What color is his poop?
Is it yellow-ish?
Does he have exposure to chickens?

It went from normal color and consistency to runny yellowish brown.

Place I bought him had many chickens housed in similar dog runs w/in 10 yds of turkeys. Here, he is housed in the barn, away from my chickens. I do go in and out of both pens each morning/evening, though.

He was fine for the first week or two. He's eating and drinking fine, although not interested in scratch feed like he was (acts like he doesn't even see or hear it thrown).

I'm not an expert or have no veterinary expertise but it may be wise to watch for signs of Blackhead disease. I know that watery yellow stool is a symptom.
I'm sure others who have more experience would have better advice to give.
