For the past couple of days i would find some nesting material and 1-2 eggs busted on bottom of coop floor and it must be one of them doing it, but i cant figure out who or why? Could it be the nesting material i use pine shavings? Btw they are 24 weeks old they just started to lay theres 5 but i think only 3 is laying cause only 3 eggs a day right now, Hopefully someone knows what i can do!! Thanks
