I am in the middle of the construction of my chicken run. I dug a "hole" in the ground the length and width of my run on a slight slope (hopefully to aid with the drainage of rain water; multiple water hose tests on the bare dirt left me pleased with my efforts) that averages between 8 and 16 inches deep and I filled it with a sand of an irregular particle size (as recommended by many different chicken resources online). Now, my question is, do I need to compact the sand? I do have a (hand) tamper (tool) or I could rent a plate tamper (though I'd rather take a hot poker in the eye; I checked this morning and it is going to be both heavy to load/unload and more expensive than I would like) or is it best just to leave the sand "loose"? Any advice from a seasoned sand chicken run builder/user would be appreciated beyond measure.
