Makes sense. When my quail ARE running around, they usually don't do it on the floor with the vents on the floor, altough one could fly into the ceiling vents, but those are screwed coversIf this really happened you should let us know. You may need to call a professional to take stuff apart. Even then I'm not sure he can get it out if it doesn't come to the opening willingly. My cat got in ours, but she was able to find a second air vent we could pull off and pull her through. As previously stated, dont leave it uncovered if your quail are running around.
