Hello. I am moving into a basement, and was going to custom build a new cage for my 2 growing beardies. Then I saw the window well and thought, "that would be so great if I could turn that into an enclosure." So, I have a few obstacles to overcome in order to do this. I live in Utah so the temps range from 110F in July, to -10F in Jan. (Beardies like a basking spot of 100-110F, and 80-ish elsewhere). The well is shaded probably 65% of the day. I am thinking of building a wood frame to fit inside the well, which I could then insulate. The real problem would be the opening at the top. Would it be enough to do 2 covers with some space between them? Does anyone know of a certain cover that would do the trick? Any custom lighting ideas? Let me know what you think.
