Actually I did spend a few hundred dollars on a chicken coop once, but then built a couple after that.
Yeah, and that's sensible, because you're doing it for eggs instead of a Status Symbol. I'm not judging you for that, I was just alluding to the fad that was so last year:
Chicken shit is also a great fertilizer, as well as eggshells to enrich your compost, and make for a more sustainable biome. My mom used a Rabbit Hutch much the same way, I thought that you planted "Rabbit Seeds" to make more rabbits, since they multiplied so quickly. We didn't get eggs out of it, but we did get a lot of Rabbit on the table. A lot easier to skin than plucking chickens.
She didn't make it look like a Vicrotian House, though. it wasn't decorative, it was basically just a 2x4 box, with chicken wire, and an enclosed side for them to keep warm in. Not unlike a chicken coop.
Back in the day, it was Pigeons, and rooftop gardens in the New York metro area. Or "Doves," and they served "Squab," because pigeon doesn't sound as hoity toity.
