I'm assuming those are just some fancy line of bronze right? Never heard of them.
I do keep both rio grandes and merriam wilds though.
The easiest way to tell them apart is the bone structure. Wilds are very slim and streamlined birds with fine bones, whereas ALL domestic turkeys reguardless of color or line are heavy thick bones bulky birds.
Just pick one of each up and feel their legs and wings and you'll instantly see what I'm talking about.
we were doing my NPIP test last year and as we were holding them, the tester said it just as we grabbed the first bird, he said, man something's different about these guys, they must be wilds.
Color can be very hard in some cases, though I can look at one and tell right off, but it takes someone familiar with what they are looking at. That's why there are so many frauds on
ebay selling 'wild" eggs for high prices when they are really nothing more than heritage bronze.
So color really wont help much, slimmer build and 1/2 the bone thickness, actually a totally different bone structure alltogether is the easiest way to tell.
legs will be much skinnier, and the toes and feet much finer. Compared to wilds, domestics are built like tanks.
Also the wattles on domestics are much heavier and looser on them than wilds, beards are often much shorter and curled too on domestics. Domestic spurs will be often much rounder, shorter and blunt compared to a 1- 1 1/2 inch stabbing tool on wilds legs.
Leg color is often much brighter in wilds too .
Hope that helps
