We are first time chicken owners. My children's third grade class had a chick incubator in their science class and they hatched chicks. We brought two home. They are Ameraucana's. We were told that we had one hen and one roo. The one on the left is supposed to be the hen. Can any of you tell me what you think? Both chickens have bumpy ridges on top of their beeks, but the one on the left is redder. The man who provided the chicks told the kids that when the chickens are about 4 weeks old, you can hold the roo upside down by his feet and he will fight to get upright. The hens will just stay there. Well, we tried it. The one we think is the roo (on the right) fought to get back upright and the one that we thought was a hen (on the left) just layed there. Is this a true indication or an old wives tale?
