I recieved my first batch of chicks ever earlier this month. They hatched March 30th and included a variety of Orpingtons. One of the BBS Orpingtons I ordered is clearly black, but she looks very different than the others, including a very long neck. Is this usual for orpingtons or maybe a sign she is a he? She is much fatter than the others but feathering out more slowly too. None of my other 4 orpingtons have a similar build.
