We were given six baby chicks and told they were Barred Rock. So I googled Barred Rock chicks and they did not look anything alike. Our little chicks were a pale yellow so I thought they might be Leghorns... I'm not sure how old they are but I'm guessing they were about 8-10 weeks old when we got them and we've had them for 8 weeks, so I think they are about 16-18 weeks old. I gave 2 to my sister so now we have 4 white chickens with red combs... i suspect they are all males, though.
