It wouldnt be easy to get chocolates from a chinchilla you would need a chocolate buck which I think would produce a load of agouti tans. Then you would probably put the female offspring back to the chocolate buck and you would get a mixed litter which might have some chocolates in but also chocolate tans, agoutis, agouti tans, cinnamons and cinnamon tans. Its sort of an awkward way of going about producing chocolates.
