Please don't assume. It's not just by THIS experience. I have spoken with multiple long time Swedish Flower Hen breeders. They are the ones that had pointed it out and informed me of their vaulted skull deformity and why you don't breed crested SFHs together. I then researched further and found out that this is common knowledge amongst the SFH breeders to not breed crested to crested. There is plenty of proof and examples that vaulted skulls occur in the breed. Just search this forum! I'm sorry, but you are mistaken and you have been lucky to not get any vaulted skulls from your breedings.I am sorry for you @KW Farms. You should not judge the breed by this experience; it sounds from what you say that what you got were not actually SFH.
