That's a lovely set up @Hanlou but I definitely think we'll go L-shaped because 1) the piggies get a big rectangle twice a week at playpen time, and 2) (more importantly) I'm only 5 foot 1 inches tall and I need to be able to reach in and do the poop scooping and feeding!
Yep I’m only 5’ 2 so I know what you mean! I had to keep a pair of garden shoes next to the above set-up to be able to get inside it to sweep poo and clean lol!
ETA - I think a set-up slightly raised up is easier for my back too. Which is also easier with a rectangular set-up!
