I would like some input as to whether you think a double wide kings cage would be large enough to house a Congo African grey on one side and a blue throat macaw on the other side and both of them not feel crowded
This is the double cage I use for my Long Billed Corella and Red Tailed Black Cockatoo. Even though they spend most of the day outside the cage, this is still spacious enough for them to spread their wings and play in.
A Congo should be fine in it, as long as you are taking it out constantly. I am not sure about a Blue Throat Macaw. They are allittle larger, but should be alright if you are taking them out alot.
It definitely looks big enough! The only concerns I see is that macaws can be sensitive to dusty birds and if they don't get along, they could still harm each other through the cage bars.
