This is our first time with chicks as our city just recently changed the rules for having backyard chickens. We got 4 females from the feed store, each a different breed and they are developing wonderfully. However, "Tina" (my son has already name them all) has us concerned because she hasn't developed any tail feathers yet like the other three. Normally I wouldn't care if we got a rooster but the city law specifically doesn't allow roosters, only hens. Can I get some help to determine if Tina should be Tony so I can call the feed store and figure out what to do.
