Okay, here is a rough idea. This is what I'm thinking for my 3 silkies and possibly a few more. If I get ambitious, I'll put the nest box on the outside. But right now, I'm feeling really lazy and just put it on the inside. I'm sure once I get started, I'll change this. But this is the general idea and the "hutch" design I'm going with. Whether or not I put the nest box on the outside, this is pretty much it. Looks pretty easy, I'm thinking it should take no time at all. It's only 4 foot tall. Easy!
