this has been such a fun resource to use, have had my girls for about a month and been making a few adjustments. Just added a thicker roost per someone's suggestions here - seems like when I was researching specs on building my coop, I never came across a recommendation for width of the roost, so I just guessed broomstick size - wrong! I also pounded a few thin nails along top edge of drawer which serves as nest box. I am going to work on training my girls to use the roosts. Sure hope this works as I have chicken sitters coming next week and I am guessing they will find poo in nest and on eggs rather unpleasant!
