Yes, the other cages (not cage) are in different rooms. However, particularly when I haven't got them in the avairy, like now, I often let all the birds out for a fly. I also move the birds in the cages around often, to be in different cages with different birds. What I meant was, should I keep these two isolated from the other six for a week or two, to make sure it isn't a disease or something?
