I just know I am wasting my time here but here goes .......... someone might be genuinely interested rather than wanting to prove a point.
how do chinchillas live in herds if they can't stand each other as pets?
Quite easily - chinchillas are generally gregarious creatures. In the wild it is asserted that they live in colonies with one male to several females (there's references for that but I can't find them just now). However we put them in an artificial environment and expect them to get along together.
One of the issues is space - a colony/herd needs plenty of space to get away if there is aggression - in the wild they would simply chase out the "unwanted" chin. In our domesticated environments this is simply not feasible however large cages do help.
Another issue is hidey holes - again, in the wild the submissive chin would run into a hidey hole (crevice or small hole) and defend it against an aggressor. In domesticated environments it is possible to provide suitable hiding places for chins.
A further issue is choice - humans impose the make-up of members in a herd/colony. The chinchilla cannot choose who is in their cage and who is not. In some ways this is "unnatural" & can cause the chins to fight.
It's all fairly basic animal behavioural stuff TBH
I think Ash's comments are interesting - many people successfully pair up chins and have no problems at all. They just don't come onto the forums shouting about it - we see the problems and the fall-outs but not the stories of chins snuggling up happily together until they die of old age.
I think one of the major factors in chinchillas fighting is a change in "balance". Something will trigger a change in power or dynamics and that "thing" can throw off years of peaceful coexistence in an instant. Suddenly chins that have been happily snuggled up for years can turn on each other and rip each other to bits - often with no warning.
Common issues which can trigger fall-outs seem to be:
Hormones - the boys coming of age & wanting to be "top chin", females with PMT, females going into season/oestrus, pregnancy (e.g. females turn on the males)
Environmental changes - moving cages (from one place/room to another), putting a new neighbour alongside an established pair/trio, moving established pairs/trios to another cage
Introducing new chins - whether that be in the same cage/room/house or just trying to get a third chin in with an established pair.
Dominance and bullying from inappropriate pairings - for example one chin gets too overbearing and bullies the other - something "snaps" in the bullied chin and all hades breaks loose.
It's more hormones but this deserves a separate mention as it is a common problem:
bringing a female in when there are paired males - this can trigger horrific fighting which often leads to fatalities.
Illness - one or more chins being ill can massively tip the balance, especially if it is the dominant chin which is sick.
Knowing the chins helps so that small scuffles can be detected but often chins fight for no apparent reason - it is often the smallest of things (like some of those listed above) which trigger fights.
I guess the bottom line is every time a chin gets put with another it is a risk - a calculated one, but a risk never-the-less.
I've got one of
the most laid back male pairings here at Monty's Manor - they are in a room with breeding chins & paired females & not a cross "kack" has ever been "kacked" between them. They were paired up at 9/10 & 7/8 years old when one of the first boys from the original pairing passed away. It was the easiest introduction ever & the boys have gotten on like a house on fire ever since - in fact, as I look now, they are on top of one another in their hammock. :heart:
I have to say the original pairing was also incredibly laid back - once again, never a "kack" between them and they lived happily together for 8 years in with the breeders/females etc.
Do I feel complacent about that pair? Heck no - they could fall out at any time. But somehow I doubt it after all these years - neither of them has a bad bone in their bodies - I still monitor them though.
My friend, Debbie, on the other hand had a pair of sisters who lived together for 6-7 years and then suddenly fell out for no apparent reason. She got them back together again after a brief separation and they lived happily until they died of old age. *shrugs*
