I have a mix of Araucanas, Lavender Orpingtons, and Blue Laced Red Wyandottes. They are 3 weeks old. At 3 weeks old I see some changes taking place...however this is my first time raising chicks so I am not sure what to look for. I would like to find out as soon as possible who are pullets and who are roos. I have a few gut feelings about a few being roos I wasn't planning on keeping any roos, they were going to be raised up to be butchered. Also would be my first time butchering anything. Now I find myself getting attached to them. If I posted pics of them would experienced BYC members be able to sex them with some accuracy, or are they still too young?
