I have nine hens. Right now none are laying as most are growing old. That’s OK - they are pets.
It really doesn’t save any money to have hens versus buying eggs. It actually costs quite a bit to feed them, especially in the winter. My nine hens will eat about six quarts of feed a day in winter, without having free range available.
Mine live in an Eglu Omlet house with an attached run. I can move it around the yard to a fresh area in the summer and protect the hens from predators. It’s also a very warm little coop in the winter. It is hard to clean in the winter, though, because the trays freeze closed. I’ll have quite a clean up when it finally warms to the fifties.
