Actually built out the bottom to house a juvenile red foot that was dropped off at the vet clinic, so has a barrier most of the way around, but I should add to bottom portion of the door.That all looks pretty fantastic. I love the pond feature!
You need a visual barrier around the bottom of the hutch house to keep your tortoises from rubbing on the hardware cloth.
I would remove the moss form the YF enclosure. It is likely to be eaten and it can cause impaction. It serves no purpose anyway.
