I have a hypothesis though. These White Leghorn chicks are feathering at different rates. Two have long wings that are the same length and are feathering at the same rate as the other varieties in the brooder, and two of the WL have short wings and are feathering slower. I hypothesize that they have the slow feathering gene that allows for feather sexing. I am marking the chicks to see if my theory is true. I am thinking the two slower feathering WL are males, and the 2 faster feathering WL chicks are female.
@Amer?
I gotta get pictures.
