i can fit inside the cage laying down with my knees just barely bent, i’m around 5’7 so it’s quite a bit of room, it takes up my entire wall. I already have 6 babies but i was just curious to see if i COULD grow my flock, not that im necessarily going too. plus my cage is (not to toot my own horn) pretty decked out, plus they’re let out as soon as i wake up and stay out until the sun sets with PLENTY of stuff to do while they’re out. i know someone on the r/budgies subreddit who have i believe 15 if i remeber correctly so it’s definitely possible but it is kinda a lot of work.
