I have 18 laying hens and 4 nesting boxes for them. Somehow, they created a fifth nesting box under the horse I put in the pen for them. Yesterday when I got home after work, I found 9 eggs from their faviraite nesting box, the one under the horse, and 4 eggs (one each from two nesting boxes and two from one nesting box). I am amazed how they can make their schedule to lay 9 eggs in one nesting box. All 9 eggs are very close to each other, but not on top of each other. I love my girls (11 BR, 5 BSL, and 2 butter cup)!
