I am new two chicken owning and after having my two new chicks for just three weeks I already decided I needed another one. All three are the same age, 2 months, and are from the same shipment which my friend raised through the heat lamp stage. Anyway, I was hoping I could just throw the new chick in with the other two, but no such luck. The 2 originals, a Barred Rock and a Red Star, went at the new chick, a Black Australorp, so I've had the Australorp separated for the last few days by wire in what will eventually be the nest boxes. I've noticed that when I let the chicks outside together the Barred Rock still goes after the new girl, but the Red Star doesn't anymore. The Barred Rock is definitely the dominant one, but I'm pretty sure the Red Star by herself would be okay with the new chick. So my question is does anyone have any experience or think it would be helpful to keep the Barred Rock separate and leave the Black Autralorp in with the Red Star? Thanks, any advice would be appreciated!
