It was brought to my attention that Williams-Sonoma was selling chicken coops (photo 1) for $1,500 US. Holds up to six hens.
So it got me curious. Looks like Walmart even carries them (photo 2) for a bit less than $1,300 US. Holds 5-6 hens. Though they have coops, non tractor for around $300 US
And last but not least, $100,000 (Photo 3) chicken coop from Neiman Marcus granted it is in the fantasy book, comes with books and a chicken specialist that will decide what breed of chickens are best suited for your area. $3,000 is donated to the ALBC. It also has a chandelier.
If you have the money, to each their own. Realistically these can be built for under $50 US, exception of the last one, and I have no clue where to start on that.
