We have 2 coops connected by a large fenced in chicken yard. One of the coops is a remodeled barn stall we put a outside door on and opened into the yard. For a few months now I've noticed something strange going on in that coop. Eggs keep getting thrown across the coop and smashed into the wall opposite the chicken nests. The pine chips keep getting dug out of them too. None of the chickens roost in that coop and they aren't fed in it. A few of my hens prefer laying their eggs in it though. Something is also digging holes in the floor about 2 inches wide. I'm the only human going into it at least that I'm aware of. The other connecting coop where all of them roost is never bothered. I was thinking rats but would they have enough strength to send eggs flying that far? It's about 12 feet across. I'm not finding any rat droppings in the nests or seeing any other animal droppings. We closed the coop off today and set out rat traps just in case. Forgot to mention during this time I've had 2 roosters die for no reason we can find. No marks on them.
