My precious Black Australian Swan, Gracie passed away today. Can't understand why. They are so well cared for. Gunther was at her side even nudging her with his beak. I'm devastated...can't quit crying. I've read the mate can sometimes grieve itself to death. Please tell me that's not the norm. Have no idea what to do now. I'll probably be up checking on him all night. I have no idea what to do now.... I'm sure he needs a companion be it female or male. Any suggestions?
