I have a thought that both Jessie and Anna each have a boy who is not going to sprout horns this time. Jessie's faded red (now white) boy Krys and Anna's boy Owen (I almost said "Gimble" - they look that alike) are both just not growing horn buds the way the rest of the boys are. Rex and Pan are sprouting horns, and they were born the same day as Krys. Owen is four days older, and shows no sign of horns beyond a slight raising along his skull, which is the growth bud, not the actual horn. Owen's brother Ari's horns have erupted completely now, as have Cerryl's.
I have a standing purchase offer for any hornless doe babies in this crop. So, of course, the one girl who might possibly *not* sprout horns - Jessie's daughter Zoe - is actually going to have horns.
