so, a little background; i have 2 parrots, both less than a year old. one is a gray male cockatiel, the other is a pineapple female conure. they are housed in separate cages and all interactions are supervised. i am interested in getting a pigeon for my birthday- hopefully, one from a breeder. i would keep it in a large/medium dog crate with various accommodations for it (platforms, toys, etc). it would receive proper veterinary care from an avian vet, be tested for any illnesses and treated/quarantined if it had any. the issue: the people working at my local bird specialty store say that i can’t have a pigeon and parrots, because the pigeon will carry diseases that could kill my birds. the question: is this true? i’ve never heard this before from anyone. i’ll be asking my pigeon keeping friends too, but i thought it would be good to ask here. EDIT: both of my birds have been tested and are perfectly healthy.
