Chicks are a new adventure for us, these are our first! we got 4 silver laced wyandotes, and 2 we were told were auracanas. they are about 2 weeks old, and everyone is developing tail feathers but one. It is also one of the larger chicks. Everyone is eating, drinking, pooing just fine. Should we be concerned, or does this mean it's a roo? As soon as I can, I will get some pictures up. Thanks!
