Well my chicken wasn't laying in it nesting boxes so when it was around the time to lay a carried her all the way to her nesting box and plopped her now she layed every day in there but stil poops in it !!!
Well for me I change the straw about twice a month or thee if it gets to poopy and when I clean it out I just out it in a big bucket do it al fits thèn my dad brings it to the municipal yard oh and for there dirt bath u could just get a sandbox and fill it with dirt or if u have a unused garden...
I have plastic on the floor but then I put newspaper on top but they totally tore it up and it was really messy !!!! So instead of newspaper I found out dry straw works out really well it absorbs the wet sloopy poops so I would recommend straw
Sorry I don't have a pic right now but I will try...
