temporary minimum cage size for ringneck dove

[broody rooster]

i am getting a ringneck dove later on today to live with my mourning dove but the only cage i have is a 17 inch tall 15 inch wide and 15 in long should i keep her in this for a day or could i place her in his cage

Is put her in the separate cage for a while in case she has any disease or something. Could you put her across the room from him so she can see him? The cage size sounds fine for a couple days.
