Been a while since I had mine but, I had an omlet eglu which I build an enclosure around. My only negative to timber structures is their ease of cleaning. I used to steam clean the eglu out once a week and steam clean it once a month, never had any issues. When my chooks eventually passed on we sold it on eBay with very little difference to what we paid for it. I call that a win win.
A pocket knife is not a weapon in the right hands it’s an essential garden tool.
