I have been browsing the Learning Center articles and have read the one about using sand in the coop. I have a few questions so please hear me out and give me your advice if possible: 1 - What is the estimated cost of river sand in Australia? 2 - If I was to add a sand floor to my coop, would I first have to shovel out the dirt floor? (I have a relatively small coop with a floor of densely-packed earth which has an annoying tendency to retain moisture. As a result my chickens are standing in a lot of mud during the rainy seasons and their feet become filthy.) Can you help me?
