Just wondered if you have found the title of this thread to be true, or if it makes little difference. I thought maybe if they start crowing earlier it might mean they have higher hormone levels and propensity towards being aggressive later in life. I have a 2 month old silkie that is super friendly and has started crowing already. Another of my hatch this year is over 4 months old and I haven't heard anything out of him yet. If my little 2 month old wannabe rooster is going to be aggressive, I want to make sure I don't get attached.
