question on pinless peepers/misbehaving hens

[Cryss]

I had to euthanize one chicken due to old age and sour crop. Left me with one Red Sex linked that attacked new chicken (scalped Austrolope) out of pair of pullets after week of introduction. Chickens were separated two more weeks and Red has pinless peers. How long do I leave them on? They work as no more fighting and she does not pursue them in attack any more. She has had them on one day.

I left the peepers on my bully for several weeks. She adapted to them but moved too slow to bully anyone. Eventually rehomed her and they removed them without incident. Of course the bully was now in a flock of about 200 instead of 6.
