12 of 24: A featherless chicken is seen in this undated handout photo from the Hebrew University School of Agriculture in Rehovot. Israeli researcher Avigdor Cahaner is breeding a fowl that will stay cool in the Middle East and other hot regions. The school has several dozen of the new chickens, a crossbreed between normal chickens and birds already balding because of a naturally-occuring "naked neck" gene. ( Photo)
