Chicken wrangler here. This may be true of supermarket eggs but should not be taken to imply that all eggs are the same.
Perhaps there isn’t a huge difference between the different labels available at the supermarket.
However, I’m incredulous that there is no difference between an egg laid by a backyard chicken who is well cared for and has a varied nutritious diet, and that which you’ll find at the supermarket.
I realise you (and youtube guy) are not talking about backyard eggs, but just because “pastured eggs” are not significantly different to cage eggs, that does not mean that it’s not possible to buy proper eggs.
