Hey guys,
I got three/four little questions 
1. How can I clear a cagetrap when I caught an animal in it to bring it to my butchery?
2. What do I have to do, to butcher an Animal I bought from one of the caravans? I bought an vulture and put it on one of my pastures but in the z-Animals-menu it doesn't appear.
3. Are there any special conditions I need to fulfill for my marksdwarves to train in the shooting range? I got enough ammo and from time to time on of them shoots but most of the time they're chiling in the canteen. Also none of my soldiers sleeps in the dedicated barracks. They're all blocking the beds in my dormitory while the barracks are always empty.
I hope you can help me 
1. not sure, i only butcher tame animals
2. pasture it, then (v)iew it, you may have to then look at (p)refrences, and then ready it for (s)laughter
3. i think you need an archery target for each squad member. when they train, they do other activities than just the range, so they wont be shooting all the time. in the schedule, make sure you have the squads set to sleep in the barracks at will or need (not sure about the differences there) and that the barracks is designated for that squad to sleep in.
