Really my only point about trios (or pairs for that matter) is that if your eggs all come from a particular breeder who only HAS one pair or trio of that breed, then you know that your chickens from them are either half of them full-sibs (in the case of a trio) or ALL full-sibs (in the case of a pair). As opposed to if you're buying from someone producing large amounts of eggs/chicks, in which case chances are that few or none of the birds you got are really all *that* closely related.
