So......... my sand is now spongy. Folks said it's a drainage issue and sand is still the best for the run. My run is 500 sq ft. Too big to cover. I agree the sponginess is due to drainage. A dry week does not dry the run out. I'm sick of spongy. I feel sorry for the hens who have to live with it. Some of you must have built a coop on land that doesn't drain well. What creative ways have you dealt with it?? I am about to undertake a massive run correction. I'm almost at the point of thinking gravel would be better in bad drainage areas. I'd hate that for the chick's feet. When it's dry, they love dust bathing in that sand. And I wonder.... you guys have such good advice.... I wonder if, with about 5 inches of spongy sand down now, can I successfully just dump gravel onto of that sand and then maybe a layer of sand.... so it'd be spongy sand, gavel, good sand. Go ahead and tell me I have to shovel it out - I can take it Just don't wanna..... Looking for easy fix.... Thanks you guys!
