I have good rates with shipped and horrible rates with shipped. It's all about the quality of bird you are looking for. I wanted relly good, type orpingtons...not too many around here so i had them shipped. Also, if you want diversity in your breeding stock, you sometimes have to go farther away than driving allows.
Now that my girls are old enough, I will cross my various lines to make improvements and get
the kind of bird I have envisioned.
It's all about what you are looking to acomplish and how much you're willing to pay to get there.
ETA: As for incubator...I like to hatch them. It's a cool learning experience and it's a personal accomplishment to see the eggs through to a little chick - IMO. Further, I dont' have a broody hen...and there are tons of difficulties with them either way. My incubator is easier to "manage".
I also hatch, because I can't see paying a ton of money to be on a waiting list to get the chicks i want. There are very few hatcheries in the country that sell orpingtons - good ones - in any color other than buff. I know several folks who got put on waiting lists only to be told never mind - call us next year. It 's a slower process to hatch, raise, cull and breed, but it is so worth it to be more incontrol over what you are getting.
Again, it's about what you are looking to do with your birds.
