Reintroduction and distractions

[Badchickenpun]

So we have a hen with a damaged beak, we brought her indoors for about a week. We ate worried about re-introduction. The wife wants me to build a second cage to keep it seperated, temporarily, while outside to make sure there.
Heres the question.
If I make their environment different enough, and they don't imediately go on the attack, how likely is it for them to attack later, once the distractions wear off?

Fwiw, I plan to add mulch to the run, it's currently just dirt and leaves. And another nesting bar and a couple large clumps of plants...

Impossible to say.
