We have raised chickens for , well, a really long time. Fresh eggs are nice. Plus, we feed them all the food scraps. The love meat, including fish guts, clam guts, mice, etc. If you feed them, say, clam guts, limit the amount as they will taint the eggs.

Chicks (whether human or avian) are a lot of work. Once fully feathered they can go outside. Some sort of pen is nice to keep them out of tings like gardens and keep them from being eaten. A light, on a timer, is necessary if you want eggs all winter.

They may be dangerous as a young rooster we had caused my broken ankle. They do have personalities and some are dumb as Darksiders.
