I have a 6 month SLW in quarantine. My little flock of 4 is 9 weeks old. So by the time I take the SLW out of quarantine they will be 7 months and just over 3 months. I plan on moving the dog crate into the run so they can all see one another. Just wondering if since the SLW is definitely bigger than the other 4 whether that might help even out the odds. 4 smaller birds possibly picking on one much bigger bird. The other thing I was wondering is after quarantine and some intro, whether it might help to bring one of my four (the mellowest one) into the crate with the SLW for a short into and then move them both into the run? My SLW is very calm and seems very sweet. My others (the 9 weekers) are a Barred Rock (she's the one I might think of using as a transition bird - very quiet and was always the one taking care of the other chicks), a Golden Buff (she's head chick but not aggressive - just the one they all follow), a Black Australorp (also a nice chick, friendly and brave but not remotely picky), and a Black Orpington (she likes to posture but never actually does anything). I probably should be more concerned about this but they all seem very mellow. We'll see how it goes. I have another 3 weeks anyway.
