Well, speaking from experience, importing birds/eggs from the UK is not cheap and there is a lot stuff that goes into it. It's not as simple as deciding "Hey, I want some Orps from the UK" and getting them the next day. It took us 1.5 years to find a breeder in the UK who was willing to work with us. There is a lot of paperwork and coordination involved and a lot of headache and aggravation. If you get eggs, trying to get them to hatch is a challenge. Out of all the eggs we got, and it was a lot, we only hatched 2 birds. Then getting them up to where they are laying and fertile. It is a lot of expense and there is a lot time and hard work invested. We started working on the process of importing our Blues and Blacks from England well over 2 years ago. To date, we have our original pair of 100% English and they just turned a year old on 06/05, and we only have four 100% English chicks. I guarantee that we have WAY more invested than $325...multiply that times 10 and it might be close.
However, that being said, I'm not trying to get rich off my pets. If I never sold another egg, or if Clementine never laid another egg, I'd be fine with that because my birds are first and foremost my pets. If I happen to make a little bit of $$$ to recoup some of the expense, that is a nice plus.
I love the English Orps....that is the satisfaction that I get out of having mine.
