I know! I wouldn't BE sifting wood shavings if I had my 'druthers, but my lovely messy birds being what they are, my coop floor is a mix of PDZ and shavings kicked out of the nesting boxes, and giant poops from my girls. I had a poop 'hammock' that they broke, and now they poop directly on the floor...I will eventually get another poop board made, and re-do the roost, and modify the nesting boxes to try to keep the shavings IN the box where they belong, but at the moment, it is what it is.
On the other hand, my pipe feeder is doing extremely well, with very little mess, and very little stoppage due to moisture in the tubes. I'm happy with it. They pled starvation this past week, so I went in to refill the feeder, only to find it NOT EMPTY, I think they just didn't like the Purina Organic I got at Tractor Supply. They're used to King brand pellets, and crowded around when I refilled the feeder yesterday, demanding the Real Stuff... Feeder is 6" ABS, with 2 uprights with caps, 2 90 degree bends, and a horizontal pipe maybe 14" across with 3-2" holes drilled in. The pipe is fat enough that any moisture that gets in isn't so bad that it can stop up the vertical pipe, and the horizontal pipe, also 6" diameter, is tall enough that they just can't bill out any food, no matter how hard they try. The feeder was a huge PITA to fill, but I ended up getting an oil funnel at the car place, sawing off most of the tiny end, and now my big scoop just about perfectly channels food into the funnel, which nicely aims food INTO the upright pipe, not sending it all over the floor like my previous iteration of funnel did. The feeder is held up off the floor with 2 small shelf brackets which work fine, and 2 tiny bungee cords going from a screw hole, around the ABS, back to the screw hole. I have some plastic plumbers tape that I'm going to replace the bungee cords with, but really, for now, the bungee cords hold the feeder up on the brackets quite nicely for me. When the girls were smaller, I had a big cement block in front of the feeder so they could reach in, but now they just stretch up from the floor to eat.
