I started with 5 EEs, three girls, two boys, they are now 18 weeks old. Then I got 2 more pullets (1 EE, 1 SLW) who are now 9 weeks old. I quarantined them and built them a little outside pen. This week I started putting their pen out near the big girls. One rooster left this week and the one I have left is very mellow. (Their doesn't seems to be any pecking order adjusting since he left, do they neeed time to get used to life w/out him?) The older chickens are very interested in the little ones and walk around their pen, the roo makes a strange cooing sound at them. My lead pullet has tried to peck at the little ones through the wire and when I held one out to her she lunged at her. I also put the big ones in their pen and let the little ones out to walk around them. I thought I had a plan but now I'm scared to let them mix. How should I go about this? Should I let the big ones spend more time checking them out through the wire? Should I let them free range together first? I've heard of people putting the new ones in at night but my chickens wake up much earlier than I and I'm afraid they would hurt the little ones before I got out there. Also my coop isn't big enough to make a section for the little ones inside. Any other ideas and advice is appreciated! Thanks!
