I had Not heard that ...I always thought eating raw eggs was a macho thing ..
I have never wormed my chickens or ever seen any sign of worms in them .
Maybe the Apple cider vinegar in their water makes a bad environment for worms ?
I also give them chopped raw onions or hot pepper flakes or cayenne pepper in their treats occasionally
Raw egg white is also good for putting on a burn ..
I antibacterial all my eggs by putting some white vinegar in the last rinse then let them dry ..
I had a burn on my stomach & leg from the boiling hot water coming out of a pressure cooker .
( It was my fault ..I was in a hurry to do the next lot ...and opened it while it still had pressure )
I opened it & it sprayed out at my stomach & leg ....It hurt horribly ...I put a cold wash cloth on it ...
the minute I took it off it hurt again ..I searched the internet for a remedy ..
Found Raw egg whites ..
Tried it ....Instant Relief ....it stopped hurting immediately ! ...only a few spots on my stomach blistered with time .
I applied it twice a day & let it dry each time ..After a year ..you can hardly even tell I was burned there .
It healed so nicely ...
Well...with regard to m own eggs, my only concern with eating raw eggs would be salmonella. Beyond that, I could eat a raw egg with little concern...but I would absolutely have to gulp it out of a glass and I couldn't chew...not once.
