I got 6, 1yr old chickens, RIR, Americana, barred rock and red sexlinks. All except the fat barred rock sleep together in the 3 nesting boxes. Which means they are CONSTANTLY full of poo. I want them to sleep in the bottom part of coop, so I put a piece of cardboard over the entrance to nesting boxes. They seem pretty distraught about this, and REALLY want to get in! The only one that sleeps where I want is the Barred Rock, she never could get up into the boxes. I got these 6 girls about 3 weeks ago. I got an egg the 1 st morning, which I assume was already in the works and 1 other egg a day or so later......nothing since. They get Scratch and Peck layer, free oyster shell and grit. I also have one of those boredom buster bricks in there. What else can I do, and suggestions on the sleeping arrangements?
