We have been experiencing a heat wave in Nashville since midweek. Today, our hensitter discovered one of our three four-year-old birds dead in the yard. They have two waterers (a plastic fount and a bucket nipple-waterer). I have also been spraying down the area under the waterer every morning. I fear that the other two may also succumb. The dead bird was a Silver Laced Wyandotte, while the survivors are a Black Australorp and a Rhode Island Red. Also, we left today and won't return till next Thursday (six days). I don't like the idea of having her disposed of before I can take a look at her to not only say goodbye, but to inspect for hints of any disease or other cause of death. Any ideas about how to keep her remains from becoming smelly and ugly before we return? Any advice to reduce further harm to our flock? All help would be appreciated.
