We were.minding a budgie for a friend for 3 weeks. A week before he was going back home we bought a baby budgie for my son. The day the bird we were minding was due to go home he died. A week later the baby budgie also died. These 2 birds never met they were in diffrent cages in diffrent rooms. Now our fish has died also a few days later. Could it be toxins in the house we not long moved in.
