I have about 3 inches of coarse sand in my coop - the sand the the stuff that you would use if your making concrete - it has built in grit that the chickens eat - so far it is working out great - as I memtioned in a earlier post - I took a dusk pan and put a lot of hoes in it and every so often I sift the sand and remove the poop - my run is also sand and I do the same thing - only use a large shovel - sand is the way to go - no toubt about it - like the song goes - "down by the seaside sifting sand" - if your old enough to remember -
