I purchased this cage with the idea to raise my baby pigeon to full grown so he would have room to learn to fly up to the running boards. This is a perfect cage for him for the first 5 months, until he is strong enough to join the others outside in their aviary. He is 3 weeks old in photo. I am 5 ft tall, so you can see in the photo how roomy it is inside. ( I was inside to secure the running boards on one end. So glad I found this cage.
