Oh no, no, no. A 25lb bag is $10. And that doesnt go very far in my opinion. Have you considered coffee grinds? We just recently started using it and it works the same way and smells much nicer (as long as you enjoy the smell of coffee of course.)
We dont really have poop boards. Heres a picture of my setup. I put the sweet pdz under where the roost. (Obviously before I scooped it. Also, this poop was not created by these babies. My big girls are responsible for that). Never had a smell, even before I did this. But I have tons of ventilation.
