We built our chicken coop this spring and a suggestion was made to create a poop hammock under the roost bar. The hammock is made from canvas and catches the poop which is pretty easy to just scoop out of the hammock. My chickens are now 7 weeks old and have been using the roost bars for the past two weeks and I LOVE how much poop is collected in this hammock! It is actually pretty amazing and I am able to scoop it out each morning (or every few days) and the pine shavings don't need to be changed nearly as often saving me $$ as well. Just thought I would throw this out there for those building their coop now - actually it would be easy to add to any coop.
