If you have long roosts along the walls, put a droppings board (shelf type) under them, that way you do not lose any floorspace at all and can clean the poo into a bucket every morning.
You may need more frequent additions of shavings, or a deeper total layer (how much do you have?). From what you describe, quite likely adding more ventilation will help keep the floor drier and the birds healthier, too.
Good luck,
Pat
