I had a Cuckoo Maran pullet (7 months old) suddenly die last night (Sunday). I didn't see what happened, but found her in the coop at night dead on the ground. She was already stiff, but you could still move her neck. Does this mean her neck was broken? She didn't have any signs of being injured, sick, or infested with bugs. Although she was acting odd Friday night. She wasn't responding to touch or when I waved my hand in front of her face. She didn't seem to have balance issues but she didn't move a lot so I can't say for sure. I've had chickens look like they are spacing out but when you go to pet them, they have some reaction. The fact she didn't respond was weird and I made a note to keep an eye on her. I didn't notice anything odd on Saturday or Sunday. The fact she was dead Sunday night was surprising. The rest of my chickens are acting normal. I love my chickens and just want to give them the best life possible. To lose one is always upsetting. I just would like some opinions on what could have happened. Thank you in advance!
