I only have 5 canaries at the moment & one of the hens seemed to be suffering from exposure ,so I bought her in ,gave her G A & kept her warm for a few days ,the weather had been bitter & wet the flights are protected ,but I hadn't put the heating on in the shed ,I do now at night ,birds are fine ,I can't say that G A did the trick ,Iam not a vet But Id always use it in future , & it doesn't cost that much so Id recommend it .
