There is most defiantly a chocolate under tone there, however, if I didn't know better, I would say bronze. But.. we all know we don't have that here in the US.. so.. I can't say that. I have seen blacks molt out chocolate however. Im guessing these guys will, they aren't true black.
I agree that they aren't true black. I also don't think they are chocolate either. I like your bronze theory. At what age will they molt out and show their true colors? I'm new to muscovies.
