What's wrong with eggs from my own backyard hens / 'happy' eggs?
Short answer: Her brothers were killed on day one at the hatchery, and she's bred to lay ~300 eggs a year on a body built for about a dozen. The garden isn't the problem.
Male layer chicks can't lay and are the wrong breed for meat, so hatcheries kill them at a day old, typically by maceration or gassing.

The objection
“My hens are happy. They have names, space, dust baths. Who exactly is harmed by eating their eggs?”
The answer
Grant all of it. Your hens may genuinely have good lives. The harm sits upstream of your garden, in the pipeline your hen arrived through.
Backyard hens come from the same industrial hatcheries as caged ones. For every female chick, a male hatches who will never lay and is the wrong breed for meat, so he is killed within hours, by maceration or gassing. Her brothers went into a macerator on day one. That’s where backyard hens come from. Billions of male chicks meet this end every year, and buying a hen funds the hatchery that does it.
Then there’s her body. Her wild ancestor, the jungle fowl, lays perhaps 10–15 eggs a year. She has been bred to lay around 300, a rate that strips calcium from her bones and predisposes her to egg binding, prolapse and reproductive cancers. That is engineered overproduction, and she pays for it.
And the ending: laying drops with age, so commercial hens are killed at a fraction of their natural lifespan. You may never do that, but the system that designed and supplied her is built on it.
There is a consistent move, and it’s not complicated: rescue ex-commercial hens rather than buying from hatcheries, and let the eggs go back to the hens, whose depleted bodies can use them.
The “happy egg” tells the truth about this hen. What it leaves out is the rest of the system, the one corner of which contains no macerator.
