As far as nest boxes go, this is going to sound silly but I swear it's working, I use 3 gallon Rubbermaid containers. I cut an entry in one side for the doe because they are rather tall. They are super easy to clean & store, I like stackable
My woodworking skills are not up to the job & I'm having fits trying to find 'real' nest boxes that I don't have to ship in from across the country.
The biggest drawback to the containers is they are very light & some does throw them around (pre-kindling), those does get a heavier box since I'd hate to lose kits
