Mehjr10, I am so jealous of your BSF bin. It's much bigger than mine. Looks great!!
Easy to make, 30 gallon drum cut out half the lid and put about 3.5" of elevation on the back end.. Put a screened drain at the bottom end.. I roll up some cardboard and now hang it by a wire over the waste for the females to lay there eggs on. I have a good batch going now and they are just starting to crawl off. The girls are Happy.. You can walk up to the bin and hear them a working..
