I had 5 gloster & gloster-x canaries. I opened a brand new bag of gourmet canary and finch food , filled the 5 seed dishes and within 3 hours all five of my birds were dead or dying. One had been sitting on 3 eggs.I contacted the store (Wal-Mart)which sold the seeds and although the manager was sympathetic he could not pull the suspect brand off the shelves as prior to mine,he had never received a complaint. I also wrote to the company which provided the food.... after two days all I received was an acknowledgment that my email had been received and was being considered. He probably never heard a complaint because if one canary, or even two, were to die, who would suspect the food? Five,on the other hand, within such a short time, should be a red flag - it is to me.I just want to know WHATkilled my birds and to prevent it causing the agony of loss to other bird lovers. I would like to have my deceased birds and the seed tested, but don't know how to go about having this done. Can you advise me in any way?
