Currently my nest boxes are on the ground. However, I am considering rearranging my coop before everyone starts laying and gets set in their ways. I'm thinking of using/ repurposing a book self to sit NY nest boxes in so I don't have to bend over/crawl on the coop floor to collect eggs. My question how high will the girls go to nest? If I put the bottom boxes 1-1.5ft off the ground, and the next row around 3ft, will the go up to that height? Sorry, no visuals.
