So this actually happened in 2018. I got 2 chickens in 2016 and they were awesome but unfortunately one of them was caught and killed. It left my second one very sad. Eventually she got over it and she started to like me more, follow me around, beg me for treats and do tricks and after a few months she was happy again. We weren’t allowed get anymore chickens because of our HOA(they told me I can keep them until they die). After about an year from my first Ones death, we went on vacation to LA. I was very worried because she was alone and one of my friends was coming to take care of her. About 2 nights into our vacation my dad got a call saying that my chicken had died(probably in her sleep). I was devastated and the rest of my trip was horrible. My parents thought it was because of a very huge storm that may have given her a heart attack but she had been through them alone before so I didn’t think so. I didn’t want to think about what happened anyways she was buried in my backyard and I’ve never wanted to go out again I came out today and I was just near her grave or whatever and it struck me that maybe she died because she was alone. Is it possible that she thought that I had died and therefore died herself? I’m just curious to know. I really miss her.
