In principle swinging out is a wee bit safer vs predators but if it is well-made and well (multiply) latched, there is nothing wrong with swinging in, either. I am not convinced it usually makes a big difference. (As opposed to stalls/sheds/pens for larger livestock, which should always have doors swinging only *out*)
It is for sure worth having the sill be raised or removeable, though, so that bedding does not cascade out everytime you open the door
Good luck, have fun,
Pat
