Hello,
I'm a renegade I guess because I don't have dropping boards. I'd like to, I just feel that it would be too cumbersome and take up more space for the girls. Instead my roosts, about 72" total length are L-shaped along the center and the back of the 4'x6' coop. I have six standard birds and they all fit there with room to spare.
They are bedded in wood chips and shavings and every other day I'll go in with salad tongs (courtesy of the local thrift store) or a litter scoop and clean up the poo that's collected on the top of the shavings.
The trick, I think, is that the girls do not have to travel through the poo to the pop door out of the house or their water so they don't track it around. However, there may be upcoming problems with the nest box that I'll have to think about.
I live in an arid climate and the poop tends to stay fairly dry and the shavings do well to absorb the liquid.
Mary
