Since no one else has heard of Egyptian Houdans, they must really be rare, find out everything you can about them. Breed the two you have to get fertile eggs if they breed true you will have more which are the exact same looking and will continue to breed true. most hatching eggs need to be shipped quickly to maintain highest viability. Well if you hold on to eggs till you have 6 (previous post stated you woud sell by the 1/2 dozen) Most likely you are reducing % that will fully develope, after you factor in that USPS will be handleing them, and the oldest being 6+ days old I wouldn't want to chance buying weekold eggs, granted newest eggs would only be a couple of days old but oldest would be 9-10 days old by the time I could set them.
