Ro is fully flighted now and knows how to fly so I was looking to upgrade her cage. However, even though she has the space to flap around now, she doesn't. Her cage is 14 inches deep, 31 inches long and 52 inches high. She seems very content in it and hasn't had any stress or behaviour problems relating to a lack of stimulation or space. I'd like to upgrade her but would like a second opinion, does she need it now? She is about an inch smaller than the average Green Cheek Conure as well. Is her current cage large enough?
