i have had clipped birds in the past and flighted.
batman came to us injured but has since grown in wings and flying and for her I would have it no other way.
Home for us a is a small space.
you come in our front door and are instantly facing down the stairs, the dining area, kitchen and lounge/computer nook all at the same time. Off the lounge is our master bedroom and ensuite and down the stairs are another 2 bedrooms, a massive play area ( gym for me and bandroom for hubby ) and bathroom laundry. It is quite narrow but long and has windows everywhere that have decals on them so that batman can see them clearly. ( Michael I love the sound of your place but could not bring myself to live somewhere with so few windows!)
Batmans Cage is in a very small space between the computer nook and the dining table and downstairs in the play area she has a stand with toys /foraging for her to be on while i work out.
In our small space we have two adults, two children (8 and 4) and Sir Guiness the cat.
Even with batman flighted it works well for us though. She gets out of cage time in the afternoon and evenings which is when the cat has outside time. All doors and windows are locked and the kids have been taught not to open doors without asking. We dont necessarily bird proof out things but batman is 100% supervised when out and I find just like with the kids redirection is a big thing when needed.
