See... little chicks are no threat to George, it's Peppa she needs to re-accept into the main coop/run.So given that they are two weeks old how long do you think I should wait? Another week? The little chicks escaped today into the bigger run and came to no harm. I discovered them when I got home they wanted Peppa and she was frantic but George didn't seem to be bothered with them.
They need to re-establish their statuses with one another....it's a pecking order thing.
Might be harder than normal with only 2 hens in the 'flock', especially if George has always been top hen.
My broody was a 'middle of the flock' ranking hen, and she was fighting with previously higher ranking hens.
I wouldn't wait at all...just get it over with.
I'd supervise tho, if blood flows break it up-more than once might be necessary, but only resegregate if absolutely necessary.
If you separate them again, you're just starting the whole thing over again.
Toss around some scratch for distraction.
Peppa and the chicks should have access to their nest for retreat, but leave their area open to the main space.
Treat it like any other integration...lots of space, multiple feed/water stations, etc.
Hopefully your coop/run is large enough for the subordinate to retreat, they need space between one another.
How big is your step up, in feet by feet?
