We got 8 chicks on March 1st from the local feed store. We were told they were all female. About 4 weeks ago they all started laying but one. We know she isn't laying because we have only 2 blue egg layers and we have actually seen the other one lay. We get one blue egg per day. The one who is not laying is smaller than all the rest and tends to stay off by herself. The others are not mean to her, they actually tend to "herd" her back to the group and will sleep on the roost with her under their wings. Her comb is very small and barely red. She also has no waddles yet. I'm wondering if she is a roo because she has the curled down roo tail feathers and different neck feathers than the others. She is shaped different as well. Leaner with a longer neck. Ill try to get a good picture of her. These are my first chickens. I hope she isn't a Roo as I live in the city and don't want to piss of the neighbors! Is it possible to have a "sexless" chicken? She acts like the slow little sister. Thanks!
