Do these bumps mean male?

[Kyng]

This unknown breed I got as a mistaken legbar has developed these bumps on the inside of its legs, and a strange single feather by the foot - both feet. Any clue as to breed?

Also - comb - indication of male?

three weeks old.

Not sure on breed or sex but the bumps on legs means nothing both male and female chicks have those
