Unfortunately, SUPERCELL has not yet implemented any "selling" feature in regards to animals, buildings, or any other thing not related to selling crafted goods or products. If you would like to suggest things on the official SUPERCELL forums, see http://forum.supercell.net/forumdisplay.php/22-Ideas-Feature-Requests.
