Can you go to that thread and say that?I don’t change the sand, I sift it once or twice a week, and add more in after I sift. I have their whole coop floor filled with sand, so it’s about 5-6 sq feet of sand. I top off the sand after I sift, I know a bunch is lost in sifting because it gets stuck to poo, but I think they eat a bunch too lol. Honestly I don’t know where all the sand goes.
