The breeding thing makes sense. I've been trying to introduce the two for over a year. I worked every day for about two months, but it's gotten spread out over time. If the two were trying to kill each other dianah, what did you do? Keep putting them together? I don't want to believe my first could kill my second, but about a year ago I let the two run together and she bit the second one (no injuries, just a fur-slip).
separated them as soon as he went for her (he wanted to kill her, she didn't want to kill him back), had breaks between meets, tried different arrangements - taken them to a different room (that made a huge difference as chinchi thought the chinchilla room was his room and that was it, there were also all these new things to explore), scattered chews around, put sand baths around. swapped fur/poo/toys/houses between cages, shared dust baths.
some chinchillas never get on.
however, have you thought breeding through? if you manage to bond a boy and a girl, you will have to separate them just before birth so the girl doesn't get pregnant straight away as this is not a good thing. so now you've got two cages. then you'll have kits, at 8 weeks you have to separate boys. they cannot got in with the dad unless you have a completely separate area where they cannot smell or see the girls. if you don't, then the dad will have to stay separate and the boys can stay together until they're 4 months old, then you'll have to separate them too (what if you've got four?). girls can stay with mum (provided they get on) but obviously you cannot put dad back. you may not be able to reintroduce dad back to mum after the separation. most people have 2-3 litters a year. chinchillas can have up to 6 kits although 3 is more usual. this is just the framework should everything go well.
if you are too busy to spend time with your adult chinchilla, will you be able to hand feed the babies every two hours, day and night for up to eight weeks? i got about half an hour sleep between each feed, thankfully i only had to do it for three weeks and my work was very understanding. my kits were accidental (fluffy was supposed to be a boy) and it was extremely stressful to go into that room wondering if you're going to find a dead kit or not. they all pulled through but i looked like i'd been hit by a bus.
this is also a longterm commitment, someone had mentioned that their 18 year old was pregnant. where are the kits going to go? is your vet experienced in performing emergency c-sections on chinchillas? are you prepared for the mother to die through pregnancy/birth complications? are you prepared for kits to die? i am not being mean, but these are all very common possibilities and you need to know before you make that decision.
also, do you know the history of your girl? i think the standard is to make sure there's no genetic problems spanning through past five generations.
