Our flock of 5 is 23.5 weeks old now. No eggs yet, but they are definitely checking out the nest boxes... Put some wooden eggs in a few of the boxes about 5 weeks ago. 3 weeks ago, we started noticing that they kept emptying one of the boxes of all bedding/nesting material (a mix of straw and pine shavings), leaving the wooden egg on the floor of the box. 2 weeks ago, they started doing this to every box, but only about once a week and all of the eggs always remained in the boxes. This week we have found the boxes devoid of all material AND eggs twice. The one egg was in the middle of the coop. The other egg was outside of the coop, on the ground, and six feet from the only door they could have gotten it out of (pop hole)! The other time the eggs were all in in the coop and out of the boxes. Additionally, they have to get the eggs over an approximate 3-inch lip of wood to even get them out of the nest boxes. We don't immediately replace the nest material, either. If they want it out, it's alright with us. We only add more when we clean out the old material or when we redistribute whats in there once they form bare spots on the floor (so approximately every 4-6 days). So what in the heck are these birds doing and why are they rolling the eggs around? I'm not sure a real egg would take kindly to these antics.
