I have golden laced Wyandottes three are crowing like roosters at sun rise. What age do the spurs develope ? I will try and post pics. Well i can not post pics yet. No spurs at about 12 weeks. keeping fingers crossed that they are hens. Bought from store that sexed them prior to my purchase. We want hens only. you can see pic @ https://www.backyardchickens.com/web/viewblog.php?id=104110 or click on My BYC page.
