Hello, we will hopefully be newbie chicken owners soon. Just need to coax hubby little more! My question with only getting 4 is do I get 4 of all one breed? 3 of one breed and 1 of another? or 2 and 2? Our breed choices from local store are EE's and Red Star. Those are the two breeds I have decided on. Just wondering if 3 Reds will pick on the 1 EE? Thanks so much.
