It seems a fun idea to have a house-swap for vacation between chicken owners. I would love to do it, only how do we figure out that the other chicken owners are not psycho.
I mean this respectfully, but it would be a great idea. I actually typed in "vacation" to see if this occurred already. We live in Seaside, CA, near Pebble Beach, Carmel, Monterey - on the Central Coast of California. We would exchange houses for 4 nights within 7 hours of hear or longer for a 2 week vacation. We have one greyhound, one cat, and 4 chickens to care for and would want to trade with similar.
Definitely you don't want a psycho...my friend's 18 yo live at home son who was watching my chickens stayed here one night, invited people over and let them steal >$5K of my stuff. Next time I'll hire a professional pet sitter.
I had to grin at your post because I have 4 whippets and a cat, but a lot more chickens. I normally take my dogs with me on my 'vacations' which are really for their activities - racing and coursing.
