Hi There, Our local elementary school hatched eggs last spring as part of a curriculum project and we took three of the chicks. We were told they were all hens. They were born June 4, 2013. One has recently started to crow when she wants something-- ready for breakfast or wants to free range. Could she be a hen acting like a rooster? How do I tell? Here is a link to a video I took of her this morning: She's the orangey-red one. Also, any help with identifying our breeds would be great! Thanks so much. We are newbies to raising chickens! Stay to end of video to hear her/him crow. Video is just over one minute.
