That’s something you can start working on now to meet 100% of your egg needs.
Raising hens still means that someone somewhere is hatching eggs and throwing out the rooster chicks, probably grinding them into chicken meal.
If you're a chicken, do you want to live forever in a cage, or be eaten alive by a bigger bird? Neither of those choices sound great to me.
So you prefer to deny this chicken the chance to live any life because you can't make it perfect?
You want to distance yourself so far from cruelty that you don't want to let anything live until you are able to provide better conditions than any mythical god could? ;-)
