I maybe shouldn't say this but why get the chickens when you know you will not change you lifestyle because of them. You get them knowing they need to be looked after knowing you plan on trips and such. I personally feel all these arrangements should have been looked into way before you decided to get the chickens.
But now that you do have them, find somebody to check on them. Don't leave them completely unattended.
