He can have one 81 mg orally or in food twice a day. The 325 mg (or four 81 mg) is for putting it in his water to drink all day.

As far as his toes are, with gout (and I have only seen a few pictures of it) causes a fat foot with fat misshapen toes. MS causes swollen joints (ankle and hock, and toe joints.) so, it is not always easy to tell. Even some vets who are not all that familiar with it and other bone diseases, can mistake one thing for another. A PCR test for mycoplasma would be good to get. They have a panel for both types that chickens get—MS and MG. @Wyorp Rock might be more helpful about testing in NC. She is usually online late.

There are 4 labs in NC - Raleigh, Elkin, Monroe and Arden/Fletcher. I believe all of them do the same testings, but it won't hurt to call or email them to find out how to have testing done.
