I am interested in getting a pair of female zebra finches to add to my collection, and was wondering how well they could do in a cage 8 inches by 13 inches x 9 inches (at top of rounded top), because this is the size I already have.
But here's the kicker - I know such a cage is like a prison, but these zebra finches would effectively have free-run of the unused kitchen-turned-bird room (12 x 12 feet, bright and sunny, lots of stuff to perch on and nothing to get hurt on) and would be allowed free flight for at least 8 if not 13-14 hours a day almost every day unless something were to come up and I couldn't be home or something. Would a small cage like that be acceptable for two girl zebras for sleeping or for a few hours a day? I've also attached a 5 x 8 inch homemade wooden breeding box with large mesh windows to the back of the cage to give them a nice sleeping spot without taking up cage space and I've put a few small but twiggy natural perches to allow maximum perching spots but also room to fly as much as possible, and have lots of ivy tied along the back and sides for cover and to pull and play with when confined. They'd have an external water sipper bottle, but access to the sink to bathe when free (my java sparrows also effectively live uncaged in that room since I moved in here and like to bathe when I plug the sink and add 3/4 inch of water. Super easy to refresh too!)
