We calculate the parton distributions for both polarized and unpolarized octet and decuplet baryons, using the MIT bag, dressed by mesons. We show that the hyperfine interaction responsible for the Δ - N and Σ^0 - Λ splittings leads to large deviations from SU(3) and SU(6) predictions. For the Λ we find significant polarized, non-strange parton distributions which lead to a sizable Λ polarization in polarized, semi-inclusive ep scattering. We also discuss the flavour symmetry violation arising
