We're having a new coop built for our 11 chickens but I was wondering about the "everyone wants one nesting box" issue. In our case its big feed buckets on their sides for now. In the new coop I'm wondering if a long shelf with a 3 inch lip full of straw would work and help alleviate the crowding? Seriously, one day 4 chickens had crowded into this one bucket and poor Annabelle was quite squashed on the bottom lol. Any thoughts? Thanks!
