It is illegal to ship eggs to the US without all the red tape and gov't paperwork and requirements.
You will have to contact breeders in the UK. To import eggs or birds you will need someone over there willing to provide all the vet services and paperwork as well as all the paperwork required by the US customs agency. I think eggs are easier to get to the US than live birds due to the bird flu scare everyone is under.
Please note any attempt to bring eggs into the US through improper means will find your home and property seized and you will be facing criminal charges of smuggling and anything else they can find to charge you with.
The laws are designed to protect our birds. There are diseases from Europe that we don't have here. They would devastate the bird populations here and cause mandatory killing of entire counties worth of birds if they did show up. Avian influenza and Newcastle disease are the 2 biggies. Newcastle pops up in pet birds occasionally but hasn't made it into poultry yet.
Bearpaw.. If nothing else you are persistant. Pigeons, and Exotic Birds are imported on a regular basis. In fact there are brokers for pigeons who will buy and ship for you. All these birds have to come into an approved USDA Quarantine Facility and are held for a minimum of 30 days. Cost per day is between $2.00 and $5.00 per bird. The one I know the most about is the one in Los Angeles. Here's a phone # for the USDA person at that Quarantine Station 310-725-1970. It may not be current as it has been a couple of years since I spoke to them, but someone should give you the lowdown on how to get some birds into the USA.
I'm curious? Why the big push to get birds from the UK? The Araucana Standards there are not the same as ours and you would be breeding out defects to meet the US standard. This is a big country. The genetic diversity here is probaly greater and surely much easier to obtain.
I have since found out that the breeders of Great Britain will not Export eggs, or poultry because of all the complications and the mortality rate. But a few have given me the formula for getting certain colors that I want. Will see if they work with our birds.
