ill turkey please help!

[honeynajar]

Went to the coop this am - it houses 2 turkeys, 8 chickens, 6 guineas. My Tom was in the coop which was unusual..sitting by the fooddish.. I went in and he didn't budge - tried to get him to move and he wouldn't. So I picked him up and carried him outside. He Almost fell when I placed him on the ground - very weak. He immediately pooped a bright yellow poop. Staggered to the othe food dish... very unsure on his feet. Ate a few bites which is abnormal - he's usually gobbling down whatever is there. He very slowly walked back into the coop and laid down. Whats wrong with him???????? The hen is fine.
Please help!

Does he free range? Could he have gotten into something Toxic?

Yes he free-ranges. Daily. The only sypmtom he has of Black head is excessive thirst. My husband caught him drinking from a pool of stagnant water and wondered if that was the issue. I seperated him and put some anti-biotic in his water as it is the only meds I have. Thank you for any help you can offer.
