Hi, I hope you all doing well 
I have a conure green cheek (male) 3.5 years old and he's very active, but his cage is actually pretty small for him so I'm planning to upgrade it to a bigger one, the biggest one I can find on the market has a bar spacing of 5/8, while my cage has a bar spacing of 1/2, but apart of that, even that the cage has the minimum (safe) required size of bar spacing for a GCC he got once his head out of cage through the bars, so I can't understand how and now I'm very confused to go for 5/8 which is a bit bigger than 1/2 or to keep this cage?
