I have captured some troggs for the purposes of contact breeding (via a cage of wild male troggs and female troggs on restraints outside) and one particular female trogg has a tucked itself away to the furthest reaches of its restraint and is exclaiming "wallowing in misery" the other female trogg in this process doesn't seem affected in the slightest.
For some reason they are very docile (notably, as i can provide reference on request, i hypothesised with other forum members in a thread about trogg fear mechanics that they experience fear in much the same way adventuremode civilians do, and react to aggression.) and its a new world with only five years under the belt, so likely there has been no historical trogg hostilities.
I've not gone out of my way to kill any troggs to scare them away, or provoke them (though one made a charge before stopping in my cage traps, unable to determine if that was a hostile act towards a puppy+restraint down there, or bravado confidence intellectual being modifiers.)
Are there any interactions that can be made with this? Some more information to this previously unheard of to me behavior would be helpful. Providing they'll not smash them up, ill put a bed down there or something to cosy them up and soon get better quality restraints. If nothing else and i don't get a baby/breeding programme, ill sell them to the human caravan (humans accept slaves even if dwarves don't, they are that docile they shouldn't be a issue to recatch/put out of misery)
