Fife, five certainly is an excellent hatch and you aren't bragging when you post pictures of your birds, you a merely sharing. I wouldn't be willing to hazard a guess as to what color they will be as adults. There are so many variables with birds. I have birds that as chicks have gold heads with black bodies yet as adults they have black heads with gold bodies. The only thing I can tell you with any certainty, after serious study of your picture is that the two chicks in the middle will grow up to be chickens and the two on the ends will as well.
