I wouldn't know why someone would discourage you from hatching your own eggs. I'm completely new to chicken raising, and I even built my own incubator. 11 out of 13 eggs hatched just fine, though I think the other 2 could have too with a bit of intervention on my part. All 11 are healthy and I assume, happy. They are now 3 weeks old.
It's pretty funny to see them outside. When I move, they come closer to me. I even had 1 chase a cat and a dog yesterday. For the life of me, I can't figure out why either would be afraid of a chick like that, lol..
