I don't have or make any nests for my birds. I just let my birds roam my fenced backyard and they just choose where they want to hide their eggs (nest).
Give them choices.I hang a bushel basket from the side of their pen,lean a piece of plwood against the side,so it makes a leanto,and I put a xmas tree leaning in the corner.My birds use all of these methods,some under the tree,some in the baskets,and some behind the plywood,and some lay out in the open where ever they feel like.
