I put a wide board on the front... to make a second perch there.... because yes, some like to perch there... and yes, I also use a poop board that is 2 feet deep... I used plywood. :idunno
Well... when you are done setting it up... will they be walking on the board much?
I put a frame around my poop board so that it can hold PDZ, sand, or feed bags... or wood shavings.... as needed..
