Hey guys sorry to bother this late but I went to go check up on my chickens because I had heard my dog barking and I thought he maybe had saw something I went to go check and I found my chicken laying their and she was unfortunately dead and besides that I found this big hole in her back near her vent and then another bruise I have no idea why she was like this I looked around for any predators but no sign and if their was a predator there shouldve been blood but it was just the big whole and you can see their was stuff inside I never saw this before and I wanna know if it’s something contagious that might affect my other chickens because it happened out of nowhere she was fine when I went to the coop earlier please help I’ll leave the pictures below!
