Hi, We have our duck coop nearish to our patio. My husband is starting to complain about the smell, so I thought I would ask for advice. When we built the coop, I thought I was being really smart by having a hardware cloth floor so that the duck poop would fall through the flooring and onto the grass below, where I could hose it into the lawn twice a day and it would disintegrate. That worked really well the first week--except now that the ducks are much bigger, there are about 400 more pounds of poop a day (too much to hose into the lawn) and it's not even drying in between hosings, which think is contributing to the smell, and it's starting to draw flies (gross). So: If I take out the grass under the coop, what can I replace it with? I can't pour concrete or anything under it, but maybe sand, maybe gravel? Should I plan to hose the poop in, or rake the poop out? Any ideas on something I should sprinkle on there in between to keep the smell down? Just has to be safe for small kids, dogs, and of course, ducks By the way, this is an 8 x 3 coop containing 4 ducks--so not a giant flock or anything. They are confined all day until they get bigger--I am nervous about hawks--but once they are adults they will be out during the day which will hopefully help. Thanks!
