hello, the nest looks really good. did you make it yourself, and what is it made from. i would like to try and build one but i have no idea what to make it from. concrete, plaster?
It is made from y-tong [you can buy it from the store]
It is pretty easy, you can just use a scredriver to carve chambers into it, then place a glass shee t over it. There are many tutorials in the forum, so look around.
