Hi, I am calling upon some feather sexing experts here. I have 2 CL (rooster) x Red Star chicks and 1 CL (rooster) x RIR chick. I took some pictures of their wing feathers hoping to feather sex them. Kindly advise if I am correct if these are indeed feather sexible:
Following pics are of Bowser at 48 hrs. I see alternate rows of feathers so
may have to switch his name to Zelda


Here is Bowser's sister Pauline at 24 hrs. My hunch is a girl


Here is the RIR cross Peach at about 60 hrs. She did not have any
feathering at birth, so I had to wait to take her picture. Pullet?
