We have 5 chicks in a 4'x8' coop and a 5'x12' run. The run has hardware cloth buried underneath and very rocky soil on top. So when we rake up the poop in the run, we also rake up a ton of rocks. I need a better way, but after sifting through all the threads on this I'm still not sure which way to go. I like the idea of sand, and plan to start using that in the coop along with poop hammocks. I think I should be able to turn that out into the compost twice a year if it isn't too deep. But if I put sand in the run, do I have to remove all that sand and replace it periodically? Or do I just rake and scoop and leave the sand alone? We have a tiny, 7000 sf lot — no room for stockpiling sand. If I have to replace the sand in the run every so often, I'll go with a deep pile of dirt so I can till it occasionally without hitting the buried wire. Thanks in advance for the help! I'm so grateful for all the experience shared here.
