Q: How many doves would you recommend as a maximum for this cage?
Also, is there a safe heater that could be added?
A: Polly -- that would depend on the aggressiveness of the individual birds -- a question for your avian vet probably. Keep in mind these aviaries are designed for inside use, so you could use a radiator type heater or Eden-Pure type heater on the outside of the cage if you needed to supplement heat in the room.
Q: Can you tell me gauge size for the A and E walk in aviaries? I have a cockatoo and need to know if this is something which would contain him full time, as I'd be using it instead of a cage. Thanks!
A: Bars are 5mm. Manufacturer indicates appropriate for an umbrella cockatoo.
