That's how other folks on here have handled egg quality issues (though their customers are often asking for a free dozen in compensation, things like that, that make you realize they're being sketchy). I worry too that people might not understand that home grown eggs aren't going to be like the sterile, perfect white eggs you get at the market, so I've only ever given them to select family/neighbors who understand that you may occasionally get a weird egg.
As far as ACV and other natural wormers, yes many folks claim one thing or another will kill off worms, but as much as I try to raise my birds according to organic practices, if I see worms, I use a dewormer designed to treat the worms I confirm I have.
