my minotaur breeding project has become a failure. I was lucky enough to cage both a male and female minotaur a few years ago. Chained them both in a dungeon area below the third cavern layer with cage traps on the outside.
The plan was they make babies, i open the hatch and those get caged while the parents remain chained, then i wait for the babies to grow up, then i toss them into my upright spike execution chamber for living things to kill them without mangling, then let the undead biome resurrect them, let them out again into more cage traps, and then pit the new undead minotaurs into a spiked ball only weapon trap execution chamber so them become mangled generic minotaur corpses i can butcher (my game is modded so sentients are butcherable, but my dwarves wont butcher historical figures, i ended up using reanimation as a way around this instead of the cannabalism fix).
but a while after chaining the minotaurs instead of making babies they decided to go insane instead and my dwarves were constantly forced to give them food and water. i let this go on for a while because it was fulfilling their need to help someone and giving them good thoughts but i eventually got tired of dumping buckets back up (i don't make a stockpile for certain things, such as buckets or other things used by workshop tasks); plus it was a long way to go from the reservoir and food stockpiles near the surface to the dungeons below so it was wasting their time and my fps.
now it's time to put two stark raving mad minotaurs out of their misery; they'll serve DeadBerries better as minotaur roasts
edit: also my game is modded so most creatures grow up faster, including minotaurs, so this is viable
