I did not spell determining correctly in the headline and I can't figure out how to correct it. I am sorry I do not have a picture. My father, who lives in another state than I do, told me that some hens he was given a few months ago have started laying brown eggs this month. He said the hens are also brown in color, but they have no tail feathers, or "no butt," as my father put it. He said he was told they are Araucana chickens. I told my father that I thought that breed of chicken laid blue or green eggs. So I looked up some information on Araucana and I do not see a brown variety, but I did see a red variety, and they lay turquoise or blue-shelled eggs. What chicken breed has hens that are brown, has no tail feathers, and lays brown eggs? Or maybe these are mixed breed chickens with no tail feathers? Hopefully someone knows the answer. Thanks.
