I bought 4 chickens from someone and one of them she told me was a 3 month olf Ameraucana. Well, that was in May and she hasn't laid a single egg and is HUGE. Not only is she huge, she has thick, feathery feet (legs). Her legs are three times as thick as the other two. (see pics) Any ideas as to what this big girl is and also why she isn't laying? (Is there a way to tell the age of a chicken somehow?) Thanks!!
