That's sound like a good choice to me.
I have read it takes both parents being carriers for a kit to become sick.
The thing is we can't tell who's a carrier until they or their off spring get sick.
Some say genetic malocclusion will show by the age of 3, while some say 5.
So how many off spring could be produced by the same pair before a case of malocclusion shows up?
How many of those could already be in breeding themselves?
It doesn't take much for a chin to have teeth problems. Anything from a smack to the mouth, an illness or even stress. Anything that would cause a chinchilla to go off it's feed will cause the teeth to over grow and wear irregularly..
Once irregular growth and wearing starts you get into all kinds of problems.
I have seen spaces develop between the teeth and feed can get caught causing gum disease.
I have seen laserations to the cheeks from points and spurs that develop from irregular chewing.They can get infected too.
I've seen some drool at the earliest stage, while one hardly ever.
With all we know it's not enough yet.
I don't believe there is any way of knowing for sure what caused each of my cases.
Though I did see one take a good bump to the mouth and later developed.
One had a severe injury as a kit, and developed malocclusion before he was 2.
Another suffered from hypoglycemia, went into shock, off his feed then needed trims.
Though the vet is inclined to believe the jaw bumps are a good indication of genetics, I've seen them in all my cases, and don't agree.
Knowing what I know I would never buy or sell a chin from a line that had any signs of malocclusion in it anywhere.
To me it's just not worth the heart ache for me/new owner, or the punishment for the chin.
