This is my first group of chicks. I have 3 3-week old guineas, 6 3-week old chicks, 1 2-week old chick, 1 1-week old chick and 2 1-week old silkies. The older gals started flapping around this morning when I turned on the light for the day. I watched them for about 5 - 10 minutes and it seems like they're fighting for 'top chicken'. Heck, my pearl guinea is trying for top chicken, too! Any advice or things to watch out for???
