Hello All! I am looking for some advice on integrating some pullets with my old flock. I have been keeping chickens for 15 years so I have integrated many birds in with a flock, but usually, I would be integrating 3 or 4 pullets with a larger flock (6-8 birds). Currently, however, my flock of adult birds is only four, two hens and two roos (I know this isn't a great balance, it's one of the reasons I'm adding new pullets), and I have 9 pullets to add in. So this is a bit new to me. I'm sure the general rules still apply, but I was interested to hear (or read, I guess?) what other more experienced people know. Right now, my pullet flock is in a smaller coop with a run next to the large coop where the old flock lives. I have been letting the old flock free range as normal and been keeping the pullet in the run. The pullets are about 2 months old now and last night was their first night outside. They still have not quite understood the whole roosting in the coop versus on the ground in the run thing, so I am going to keep them in the small coop in the run until they figure it out (maybe 1-2 weeks, hopefully). After this, I was hoping to integrate them with the old flock. My idea was to introduce them while free ranging (I was planning on letting the pullets out first and then the older flock) and if it went well, moving the pullets into the large coop at night. I was thinking I would keep everyone at least in the run for a few days so the pullets learn to roost in that coop, but I worry this might cause some trouble. 3 of my 4 older birds are very docile, but one of my roos (an Ameraucana/Faverolles cross) can be a bit of a demon and he is very large. The pullets are all large fowl and are a mix of breeds (Buff Orp, SL Wyandotte, Black Sex-link, Black Australorp and an Easter Egger). What do you all think? Thank you!
