I would go so far to suggest that if scientific abduction is illogical, that exposes a problem with logic, not with scientific abduction. Logic has a pretty mixed history of producing accurate knowledge. For instance, Aristotlian physics.
Logic is not sufficient to determine everything in nature, but it is, I think, necessary.
Abduction is logical, it is one of the modes of logical reasoning (ie., deductive, inductive and abductive). It is not deductively valid. This isn't a problem with deductive logic - after all, plenty of physics seems to be based on the deductions of mathematics, it just means that deduction does not have a monopoly in reasoning logically.
