This quartet of Columbian Wyandottes hatched on March 11. I ordered one boy and two girls, and I got an extra roo as a bonus chick. For the life of me I cannot tell which are the boys and which are the girls. Two of them have the pointy hackle feathers that would indicate that they are boys, but these are also the ones whose backs have been partially bared by treading. One is plump with lovely white feathers, and I would have thought she's a girl, but she is also the one with the wattles. The fourth is very similar to this third, but this one has no wattles. Can you please help me determine which are the roos and which are the girls? Chick #1, "N": Chick #2, "W": Chick #3, "L": Chick #4, "M": Thanks!
