Purchased these chicks in the beginning of March. I have no idea if they are roos or hens. We got our first egg today. I have not heard any crowing yet and they are about 16 weeks old. They were supposed to be all pullets but I am suspicious. I have scoured the internet and it seems that some of the amberlink hens have larger cones and some smaller. Also one is white with a black feather. I don't know what kind he or she it. I would love some input here. We are newbies to chickens and loving it.
