Help....My Turkey is sick :(

[DCWiley500]

I have a six month old bronze tom turkey. He has been acting very lethargic and has a loss of appetite. I have given him some electrolytes made for poultry, and I've given worm medication but he's still acting the same. Any and ALL suggestions are appreciated.

Thanks,
David
