They seem to be more subject to shipping stress than some other breeds, so sometimes it can take two or three incubations to get one good group of birds, whereas say, with Barred Rocks, you may get most of them to hatch, even when they are shipped in the same box. That being said, many have hatched my own eggs across the country successfully, so just depends on many factors, as with all shipped eggs. The thing is, this is how you have to get them. Only two hatcheries sell these chicks and they are VERY expensive for straightrun chicks, IF you can get them before they are sold out for the year. They do not sex them.
