I have 4, 3 week EE chicks, sexed female.I have noticed that one of them is feathering a little different that the other three. Mainly noticed that the feathers on the legs are starting to come in and the others there's nothing yet. That one gets much more freaked out being handled than the rest and was trying to peck my hand when I was picking up the others. I just get paranoid that we will end up with a roo. We can't have one, I would be heart broken if it is a roo. What are the earliest ways to tell with EE?
