After reading about 50/50 about construction vs play sand we just bought 2 bags of each for the coop. DH put the two bags of construction sand in and it was fine-dusty but it settled fast. Then he put in one bag of play sand and it's clumpy and damp-probably because they keep it outside at the Home Depot. I know that with the horse pellet bedding, the Dummies for Chickens book says to wet it down so I'm guessing damp sand isn't a big deal? We're letting the first bag sit in there to hopefully dry a little bit before adding the 2nd bag (which is probably just as damp). Should we put a board or something so they can get off the damp sand if they want to? Also how much should we level the sand? Will the chickens level it out themselves? eta: should I wait until all the sand is totally dry before adding the DE?
