at 6-8 weeks they need to be separated, removed, from the parents. Place all the chicks in one cage now then at 10-12 weeks they should be put into pairs. The male chicks will start to growl or crow and the females will soon start to lay it is then that they need separate cages, even if you are planning on keeping all of them they are much happier in pairs. CBBQ are territorial and the males will fight all the time. Some people try to keep them in trios of one male and two females, but in the wild they pair up and are much happier.
