It sounds like a great enclosure, hope you post some pics of it. This forum has a lot of good advice but some of the members can become quite upset when discussing enclosures. There was a recent arguementative thread that went on for several pages of bickering. Many keepers/breeders keep thier bps in tubs and justify it because the bps tend to live in burrowed out holes. Of course that does not mean that they live all thier life in the same hole and do move from one place to another outside of a hole. My understanding is that there have been some observations of bps in trees appearing to hunt birds on occasion. In addition, villagers supposedly think a bp going through the village was a good omen and would not disturb them. So if it works for you and you are meeting the husbandry essentials for caring for your bp then good on you and I am looking forward to see the sectioned off feeding area.
