It’s usually not the same hen every day. Making an egg takes like 24-26 hours so if you have two hens you may get an egg every day but they won’t necessarily lay everyday

they’ve been bred over time to lay 10x as many eggs as their pre-domesticated ancestors did. it’s like having your period 10x a month. they have loads of associated health issues which can cause iron deficiencies legs breaking etc

Inside an egg-laying hen, there are about six eggs in various stages of growth. They have a voracious appetite. I have seen videos of hens going after a mouse that had gotten into the coop. Killed and eaten in a flash.

For hens, get a bug zapper, and every time a fried fly drops, they will eat it immediately.

Wild animals aren’t this productive; humans expressly bred them to produce ridiculous amounts of animal product and to instinctively rely on humans for care even if they didn’t.

So only *domesticated* chickens lay that many eggs, only *domesticated* cows produce that much milk, only *domesticated* sheep and goats need to be shorn because they don’t shed naturally, etc.

And yes, they gobble up huge amounts of crops to upkeep that production.

This also means you can’t let those creatures out into the wild to “be free”. As they are, they now require human care, or they will die in various horrible ways. Being eaten alive butt-first by maggots due to poor hygiene is a pretty nasty one.
