I have 3 week old chicks, all have different moms, ones dcuccle, ones silkie/Cochin and ones BC marans. All have silkie daddies. I am hoping and praying they are all girls, but I know the odds are not in my favor. Has anyone had any luck in sexing young chicks by their behavior? At what age does the rooish stance and attitude start to kick in? I want to avoid getting too attatched to a future rooster who must go.
