Today I was so excited to go out & find 2 eggs in the bottom nest.. I knew a couple girls were getting close to start laying, so now I guess I have two active layers.. Like I said I have 7 birds (2 are now laying & 5 getting super close).. For the past 2 days I have went out to find eggs in perfect nesty box on bottom & destroyed nest on top. They throw the hay out of the top nest & the golf balls (found 1 out in the run today from top nest).. Why is one of my hens being a nest assassin to the top nest??? BTW we have 2 nest for 7 hens. They are super huge (I swear 3 birds could fit in 1 at a time).. Here is a pic... Should I add more or take down the top nest and sit it beside the other one???
