Partners - forced copulation

["Wendy" <>]

And when there are a group of male birds assisting/engaging in the 'forced
copulation' with a single unwilling female bird, an appropriate term would
be -
'gang forced copulation'
pack ....
flock.....
single gender flock .....
???

While this behaviour is common in domestic chooks and so may be dismissed as
behaviour resulting from domestication, I did observe such behaviour
recently with my resident wild/feral sparrows!
