You are right.. Cheetah's tail dies make a good weather-vane. The lady is Cuckoo, and I'm guessing she's supposed to be a barred rock, but her front half looked more like Cheetah's pencilling, in silver. Speculation: (hatchery's choice assortment makes for a guessing game) she's a cross between the barred and pencilled rocks (the yellow legs). Twirp is the other mystery and I'm guessing a Whiting True Blue. I'm mostly sure she's laying blue eggs and either Splash or Blanche (white Sapphires) is laying white eggs. Cuckoo and Jessica are both supposed to lay brown eggs, but I think 1 is laying white also (2 blue, 2 brown and 4 white eggs in a day with 1 of the Brown not being pullet sized). Storm isn't laying yet, but as she hatched from a green egg with a wyandotte father, should be green-brown. muddled meanderings of a tired/sleepy mind.
