That must have been frustrating ... and more than a little heartbreaking!
And it's a shame you're so far off, because I also have five young Sebrights and some OEGB's that would make a good starter flock for someone wanting some nice banties!
We have Nankin bantams, but we were still a long way off from setting eggs, so I made the mistake of doing the "Aren't they cute?" thing at Tractor Supply ... and now I am over-run with 15-week old bantams!
Haha it is quite a shame. We used to have easter eggers and they were perfect egg layers. Even one had 6 babies! Coyote snatched our last flock. We have a better pen this time.
