A recent tip mentioned a picture where a chicken in the background went unnoticed for some time.
The chicken was not the point. The reminder was to go back and make certain that all details or pieces of information in a record (or picture) have been noticed and analyzed. I cannot decide whether or not to research the chicken if I never see it in the first place.
Of course, the chicken probably does not matter. But sometimes those seemingly innocent clues are relevant and significant discoveries are often made when one is looking at innocuous details.
We just have to remember not to get too “eggcited” about seeing the chicken.
