  We study transport in the presence of magnetic domain walls (DWs) in a
lattice model of ferromagnetic type-I Weyl metals. We compute the diagonal and
Hall conductivities in the presence of a DW, using both Kubo and Landauer
formalisms, and uncover the effect of DW scattering. When the Fermi level lies
near Weyl points, we find a strong skew scattering at the DW which leads to a
significant additional Hall effect. We estimate the average Hall resistivity
for multi-domain configurations and identify the limit where the DW scattering
contribution becomes significant. We show that a continuum model obtained by
linearizing the lattice dispersion around the Weyl points does not correctly
capture this DW physics. Going beyond the linearized theory, and incorporating
leading curvature terms, leads to a semi-quantitative agreement with our
lattice model results. Our results are relevant for experiments on the Hall
resistivity of spin-orbit coupled ferromagnets, which can have Weyl points near
the Fermi energy.
