This Rouen is confusing me. Bumble is 13 weeks old and showing signs of boy and girl. Bumble has a LOUD voice and the beak is like a female coloring and NO drake feather, no white ring around neck. But now grey feathers are coming in and there is a green shine on the head and a faint olive/purple on the top wing feathers. Bumble is also very tiny. Look at pics and let me know what you think please. If a boy, how long does it take to fully transform?
