Yes indeed- extremely addictive! I have plenty - but always enjoy hatching more! I do sell eggs at work (not for profit) and now my customers would like me to supply them with chickens too! There is a youtube video with chickens as the gateway pet... before you know it you'll have goats & cows too!
This reminds me of a Craigslist add that "rented" out chickens and a small coop for a short period of time (4-6 weeks?) - customers that rented the chickens and coop could then buy the coop if they desired after the rental period was up! Seems like a pretty good business to me!
