Go on and have fun naming them! Everyone has or has had one named a different gender name. For us, we knew when we were naming them that there was no way to know what they would turn into. DH still had his names picked out before we even got them home. We have Jake, a female rouen; also had Bonnie a rooster. You could always choose non-gender specific names. So go ahead, have fun with it! It will help them get to know their names to hear them while they are growing. If I step outside right now and holler Butter that duckie will fluff up like no ones business..
Bath time today. They are a lot of fun!!!
