You could do a quickie for now, if you want to let that orp set...but think long term too.Now I am trying to figure out if I want to make a pen inside here
One thing for sure for both short and long term, is make it easily accessible for you!
The thing I regret/bemoan the most, tho I really didn't have room to make it bigger...is that the 4 feet with a 1-2 foot poop board makes moving around in there very tight for someone whose knees don't squat anymore.
