I have never regretted getting my chickens for a second. But I have seen people who either have regretted it, threw a ton of money into a beautiful coop and then decided it "wasn't for them" and sold their chickens off, and people who just shouldn't have chickens. The most important thing is to think logicaly and reasonably, don't act on impulse. Do you have a place to dump shavings, if not thats ok, you can work out a solution, I know a guy who lives in the middle of a city, he has to throw his shavings away in a hasmat biological danger bag. Try to think of all the problems you could encounter BEFORE you get the chickens. As far as vacations chickens are alot easier than a dog, or even a cat. If I'm going someplace for under three days I won't even bother having anybody come over, but i do have people i can call in case of emergency. If you know anyone nearby with chickens you can tradeoff petsitting when you go away. As far as pro's and con's give it up, I'v been thinking about the pros and cons of chickens for a while and have come to the conclusion that while their are very few visibly possitive aspects of chicken keeping it still gives me lots of joy, and I really don't know why. There's just something about all my birds and the work involved in them that gives me satisfaction. Please don't be turned off by my post, I encourage you to get chickens, just think it through first. My chickens are the easiest birds I have, and the friendliest, I'm not sure what I would do without them.
