I would really recommend a roof that has a sloop. That same storm where I used my roof rake, collasped the run roof of a friend who had a flat roof of heavy poultry netting. You can probably find a used frame from a portable garage on something like Kijiji.I think I'll try out making a sort of roof as well, that definitely sounds like a time saver (no need to shovel nearly as much snow)
I also have peacocks. They don't seem to mind strutting through the snow so they can perch outside in the sunshine.Seeing my ducks sitting out in the snow honestly really stressed me out at first, as someone who owns mostly exotic birds I'm still getting used to their resilience to cold.
