Why not try it. I know a breeder with beautiful show chickens (Braekel) who sends eggs by posts all over Europe. He makes sure they are wel wrapped in soft toilet paper and puts them one by one in an egg carton. The full egg carton is wrapped in anti shock material again. I heard that the outcome of the egg’s varies very much. Sometimes is near to 100%, often 50% and once or twice it was a complete failure.
Make sure the eggs rest properly before you put the in an incubator or under a perfect broody hen.
The eggs are expensive of course. But if you breed them from there you can make a large group within 2 years. After 2-3 generations I think it’s best to look for fresh blood.
