I gave rice with egg to my birds and totally forgot to remove it from the cage after 30 minutes. I remember reading somewhere that eggs can only be served for 30 minutes to make sure they are not getting spoiled. My estimate that it was there for an hour and a half. When I came back, they were eating it. This is when I recalled I failed to remember to remove it.
Should I expect any problems? We are with AC now, about 76-77 degrees in the house.

It probably wouldn't go bad that quickly.

yeah, I know for a fact that we always packed hard boiled eggs when traveled on a train when I was a child. They were nutritional and didn;t get spoiled very fast, believe it or not. We never got sick.
It was probably the same person who wrote that bedding in nestboxes had to be changed every day when you have chicks or they all die from bacteria. One of cockatiel related web sites (informational, not a forum)
