Some chickens drink their own egg. Force the fresh egg open with their sharp pointed beak and sip all its contents. I am an agriculturist-food technologist but I never know the real reason behind the did. Elders said it’s because it got very hungry but never want to get out of nest. Chickens doing such are candidate for culling.
We never usually take fresh uncooked eggs. We boil it, from soft boiled egg, malasado, to hard boiled egg. Fry, sunny side up, beaten, torta and omelet. The only nearest to raw eggs is the malasado.
Note: fresh eggs is mixed with drinks such as eggnog and coconut eggnog variation or coquito.
On the other hand, some do take fresh eggs. Fresh eggs straight from the egg shells. Pricking the egg shell with a sharp object instead of beak. Then drinking it like an ordinary drinking water. Sometimes mixing a little salt to counter the disagreeable taste, malansa.
I think, fresh egg is drank as tonic. Taken by alcohol intoxicated person and or exhausted person a day after.
If the egg is a Salmonella carrier, the drinker might suffer then.
