I have to go inside daily anyway - collect eggs, eyeball food containers, make sure no one is dead, so it takes me an extra 2 minutes maybe to scrape the poop for composting. I find that I like the poop unadulterated (no shavings) for the majority of what goes in my garden.
It's what works for me. Plenty of people don't have poop boards and the poop falls on the ground or on shavings or hay, etc, and they remove it when necessary. The length of time between cleanings is determined by the number of birds you have.
