The present embodiments provide an aviary that includes a cage tower and an egg collector. A cover is positioned over the egg collector and includes an inner end and an outer end. A cover adjustment member is coupled to the cover to reversibly raise one of the inner end and the outer end to a higher position than the other of the inner end and the outer end to facilitate movement of a deposit disposed on the cover toward the lower positioned end. The present embodiments also provide a method of operating an adjustable balcony in an aviary, which aviary includes a cage tower, an egg collector, a cover including an inner end and an outer end, and a deposit. The method includes disposing the cage tower in the aviary, disposing the egg collector on the cage tower, disposing the cover above the egg collector, and disposing the deposit on the cover. The method further comprises raising, during a first period of time, one of the inner end and the outer end to a position higher than the other of the inner end and the outer end to facilitate movement of the deposit toward the lower positioned end, and lowering, during a second period of time, the one of the inner end and the outer end to a position lower than the other of the inner end and the outer end to facilitate movement of the deposit away from the higher positioned end.
