Lady Jane is a boy for sure. That is just way too young for wattles like that. I have a rooster that has never crowed, but mine usually wait until 6 months or so before they start. Once they start crowing, they are less friendly than they were as chicks (for the most part). I've found roos to be more outgoing and people friendly from the start. Hens normally shy away. Roos are meant to ballsy like that.
