yes, you have to remember these are native to the Yucatan so they are in a tropical part of the world year round, 40 will kill them.
and just about any bacteria common in barn yard flocks, will kill them.
coccidian, will kill them, pretty much, need to be lock and key bio secure .
These are not turkeys like people are thinking. They are a tropical wild fowl, put all the domestic comparisons out of your head.
If you let these out, they will be gone, and I couldn't let a $3000 pr of birds free range anyway even if they did stay around.
If you have a yard of chickens, turkeys, guineas, stuff like this, don't even consider getting them. They carry enough disease that doesn't bother them at all, but will kill these birds within a week or two.
there's a reason only 3 people in all of the US have them, and I think of those, Virgil is the only who can get them to produce.
Don't want to be a downer, but it's just the truth about this species of fowl.... save them for the pros that deal with extreme care exotics....
