We have raised a few hens at our hobby farm over the years. The eggs are nice and all, but they're actually quite fragile animals, and then you go and get attached to them and they get suddenly sick and slowly die on you in horrible ways. And veterinary care for backyard chickens is seriously problematic and difficult to get and expensive.
My wife fell seriously in love with keeping chickens and it kind of emotionally broke her. Always tried so hard to do things right, and something has always gone wrong.
I wouldn't advise it, personally, to most people.
Ducks are apparently a bit more resilient though. And duck eggs are great.
