Yeah, that is alot of money. Be careful when posting on craigslist. There are bad people on there. Just post you need a chicken sitter if you really want to give them a temp home and when you find the right person, then negociate boarding fees. It would be terrible for you to pay for chicken boarding and to come back finding your birds, sick, dead, injured, infested with bugs, or something else. 6 months is a long time to be away.
