I love my droppings board. I so would never have a coop without it. Just think, the droppings must go somewhere and if it's on the floor, your birds will be in it and dirtier. Plus it eats up clean floor space for them to play in. Good luck, anxious to see what you come up with.
Right after this pic was taken we tacked the linoleum to the wall with molding so it wouldn't curl and pull up. The floor is also covered in linoleum and covered with 3 inches of pine shavings which I have never had to replace yet and I added it when I got my chicks in June. I just rake it and the heavy goes to the bottom while the light and fluffy comes to the top. Doesn't stink in there either although it is winter here still. Deep litter method would be way more difficult if they dropped all their nightly droppings on the floor. I just clean the droppings board with a small dustpan at least once per week and all is well.
