I don't remember the exact data but from what I've read truly free range eggs are much much healthier idk about losing weight but they're lower in cholesterol and bad fats higher in omega 3s and 6s and other good fats.
Among a few other things I believe. Basically the healthier and happier and better fed the hen the better quality the eggs are.
You can see it by comparing store bought eggs with fresh eggs particularly from your own hens or from pastured birds. Yes some of the differences come from the age of the eggs such as the consistency of the whites and how high up the yolk stands but also the color of the yolk, which is directly associated with the amount of omega 3s and 6s. Birds on grass have darker yolks.
Yes we have offered to give them some to try. I just got some story about how they had two dozen store bought eggs at home and they didn't want my eggs to go bad in the fridge. They were that days eggs and would have been good in the fridge for 8 weeks or so easily.
My DH2B and I joke and call her one of The Croods(from the movie- favorite of some nephews) "It's new!!!!" So she's suspicious BC the egg might open up and hatch a dinosaur that will eat her. Lol. Okay not really.
There are lots of people around here that sell eggs and we have had some trouble starting up our egg business because of it. In the meantime when we get too many eggs or if they get older they are hard-boiled and fed back to the flock. They love them and it gives them extra protein and the eggs don't go to waste. Sure I would rather sell the eggs to try and offset the feed costs but I'm not going to freak out about it. I know we will make it eventually. For the time being it's worth it knowing our girls are happy and healthy and that we are going to be getting the best eggs and meat we can as we are also raising all of our spare cockerals up for the freezer.
Wow that's very strange :/ though it's a pretty common belief that eggs and ither foods go bad
