There are thousands of confirmed detections of star forming galaxies at redshifts z>4. These observations rely primarily on the detection of the spectral Lyman Break and the Lyman-alpha emission line. I will present results based on hydrodynamical simulations aimed at constructing a panchromatic picture of this high redshift galaxy population. I will show how this model successfully reproduces the observational constraints from Lyman Break Galaxies (LBGs) and Lyman-alpha emitters  (LAEs) at  5<z<7. Based on this model and recent observational results I will argue that three new elements should be considered in the interpretation of upcoming observations of high-z galaxies: stochasticity effects at low star formation rates, the impact of using molecular gas to model star formation and the necessity for AGN feedback at high redshift.
