Hi! I'm purchasing new chickens to my previous flock which is comprised of two silkie roos and one silkie pullet who have been together since birth. We decided to get more pullets because we only have 1 pullet as we got them straight run. So today I am getting two new pullets about 5 months old. Any tips on how I should take care of them? What if the roos attack them? what if they run away? What if they attack the roos?? How to I introduce them without blood-shed?? Oh and which one lays more eggs: Sex-link/ Australorpe cross OR Speckled Sussex? Thanks!! Please help a first timer!
