This is my first post in the BYC forum. I've been reading everyone's posts about raising chicks, but still have a few questions. I have 5 RIR, 4 BR, and 2 BO chicks that are 16 days old now. Everything has gone great and they're growing so fast and getting so many feathers!! My first question is: what about the size difference that I'm seeing. One of the BR is very small next to the largest BR. Is that normal for chicks of the same age and same breed to develop at different rates? They are all from the same small hatchery about an hour away. It seems that a few of them are trying to be the "queen" of the little flock. They'll jump up, flap their wings and bump the other chicks and then have a "stare-down." It's funny to watch I guess that's normal, right? Thanks for your help.
