  We report on magnetic and magnetotransport studies of a Kagome ferromagnetic
metal, Fe$_3$Sn. Our studies reveal a large anomalous Hall conductivity
($\sigma_{zx}$) in this system, mainly contributed by temperature independent
intrinsic Hall conductivity ($\sigma^{int}_{zx}$=485$\pm$60 S/cm) and
temperature dependent extrinsic Hall conductivity ($\sigma^{ext}_{zx}$) due to
skew-scattering. Although $\sigma^{ext}_{zx}$ value is large and almost
equivalent to the intrinsic Hall conductivity at low temperatures, it
drastically decreases with increasing temperature, following the relation
$\sigma^{ext}_{zx}=\frac{\sigma_{zx0}^{ext}}{(aT+1)^2}$, under the influence of
electron-phonon scattering. The presence of electron-phonon scattering in this
system is also confirmed by the linear dependence of longitudinal electrical
resistivity at higher temperatures [$\rho(T)\propto T$]. We further find that
Fe$_3$Sn is a soft ferromagnet with an easy-axis of magnetization lying in the
$\it{ab}$ plane of the crystal with magnetocrystalline anisotropy energy
density as large as 1.02 $\times$ 10$^6$
