Sorry, was offline for a bit. Busy.
It's good to hear she's going back into the group. Wonder why the rooster was going after her? Not the nicest mentality... Not something I'd tolerate in mine, but each to their own.
It's already good that your hens are tolerating her, so that's a plus. Nothing much you can do with a flock that sets upon and destroys every ill or injured (or just young) animal they have among them. Such a flock would need culling or closing, in my opinion. I cull animals from my flock for intolerance to infants, injured, or ill birds, because it's my decision what to do with such individuals, not the flock's. Healthy mentalities mind their own.
I can't have birds who will kill any sick or hurt animal because I could have fixed the animal in most cases, rather than have it wasted.
People think it's just natural instinct to destroy the weak, but it's not; that's a bit of misinformation that's been getting passed around since I was a child. In the wild, the ill and injured are left behind. When the dying animal tries to join a group it will be driven away, but expending time and energy to kill something that is already failing is not natural unless the creature doing the killing is a predator.
When we cage animals intensively and they get so bored they go out of their minds, then they kill for sport, and can feel great distress over being caged with dying animals. But it's not a healthy, natural instinct, it's something we've forced on them, and when allowed to free range it ought to dissipate... But of course it tends to linger on until culled out, long after its purpose has been invalidated.
Best wishes with your flock.
