This morning, I let Ichabod and the main flock out to free-range briefly and to give them a chance to meet the pullets. Quarantine isn't going well as the picking had been getting better with the increased protein in their diet but has now regressed to something even worse than what it was initially and as much as I was hoping to avoid the peepers, it's time to try them.
All but two of the main flock rushed past the quarantine area; Ichabod and Grace, one of the Dominique hens stopped at the pullets' pen. The two more passive pullets stayed in the center of their pen and remained there whilst Grace and one of the more dominant pullets immediately began to spar through the barrier though neither was daring enough to make it serious and the second dominant went for Ichabod. He didn't engage like Grace did but instead lowered his head and stepped forward, placing himself between the barrier and me, whilst glaring at her with his hackles slightly raised. She kept reaching through trying to peck at his comb but he kept just out of reach. When I stepped away, he followed. I have no doubt he was protecting me from what was an obvious threat to his flock (from his perspective).
This is not an integration I'm looking forward to. At all. When the time comes, I think it will be best to let the two less dominant pullets out to free range with the main flock, allowing them time to find their place in the order before introducing the other two who will most definitely need to be in the peepers for a while and may remain in solitary well after the more passive girls have been integrated. I'm not sure if this approach will make this process more complicated and stressful than necessary but I also don't want my main flock suffering through feather picking and bad attitudes, especially when everyone is finally finishing up with their molting.
