Both pictured are 18 weeks old. Originally thought the Blue was just a late bloomer since her comb and wattle haven't developed much yet (pink hue just showed up in last week), and had been comparing her to Lavender, which I always assumed was female. Lavender one has been reddish for weeks now and comb/wattle bigger. Those pointy neck feathers on the Lavender kind of jumped out at me though yesterday so thought I'd should ask the experts... is she a he?
