I want to rearrange my bird cages and unfortunately where I want to put them is the only vent for AC and heat in my family room. (Really large room and stupid placement.) I know that the air will just fan out when it hits the cage but how far from the air source is safe for the bird? For instance, the bottom of the cage is probably 7-8 inches from the vent/floor. The grate that the macaw is likely to be on is another 6 inches above that. So a total of 13-14 inches from the vent (I'm at work so I can't measure exactly). Is that far enough away from the mini macaw or will that cause problems for him?
