I am one of the ones you contacted. I didn't have any eggs available currently.
The Barnevelders are very difficult to find. I have been able to get eggs from two other breeders this year. I had two chicks hatch out of the one group and the others are still in the incubator.
I am trying to get new non-related blood in my group, however it is a problem with so few breeders.
I have hatched several different setting of eggs and there seems to have a few barnies with either crooked toes or straddle legs. The other breeds that hatched at the same time are not showing the same problems. I have hatched eggs from other barnevelder breeders and the leg problems seem to be a problem in those flocks also.
Other than this problem, they actually are pretty easy keepers and lay a very large egg. They are very lovely birds and I would encourage you to continue to looking for them. I got my first barnevelder from Ideal three years ago, however I was on the waiting list for a long time.
I will not have any eggs available until fall or spring. I am setting and hatching all the eggs that I am getting.
Good luck with your search.
