There is NOTHING natural about a modern chickem. They have been selectively bred for hundreds of generations to produce meat, eggs or both.
A natural chicken would lay maybe 30 eggs a year and raise two broods. They would eat ALL year.
Ours can, and will, lay up to 300 eggs per year. To do this they need us to take care of them. They need a first class diet and good housing. They also need additional lighting, or they will quit laying in September, and moult.
They do NOT need to do this, esp. in their first year. There is nothing cruel about this at all, it is simply good management.
Chickens lay eggs, it does not hurt them, and it is perfectly natural. We simply get them to do what they do for longer.
In the meantime, my chickens wander at will, eat what they want, when they want, and spend the night comfortable.
