I am not sure GQ, I know you have had more experience since you've had more drakes but standing beside a 3yr old bantam at 6 weeks old makes me think duck. The legs are pretty thick though, but my last duck who is 14 weeks old now has pretty thick legs for a girl. Humm
It's more the length that makes me go hmm.. heck i dunno these Muscovy are enough to drive you crazy lol Either way OP you have two choices. boy or girl for sure.
