If the universe is objectively real then either all crows are black or some crows are not black.
Observations do not increase or decrease the likelihood of the statement "all crows are black" being true. There is not a probability, only a certainty. The probability is just a fiction in the mind of the observer.
The paradox seems to arise because ishmael, the person describing the situation, cannot tell the difference between what is true and what is thought to be true.
There are subtleties I have not included here (such as the colour of crows changing over time, the possibility of people deliberately painting a crow a different colour, or the colour black not being rigidly defined), but they are not relevant to my argument.
