Yes, was wondering too!! The only Kinder I know is the moorland by us, - Kinder Scout!!
I have pygmy goats, and also an Anglo Nubian intact billy ....so the off spring will be Kinder!!
Do you have a photo of your goat? Is it out of a pygmy by a nubian? Surely not a nubian female and a pygmy billy?
Have just googled kinder goats, and am surprised to see they look like Molly one of my smaller goats. We use our pygmy billy on her, and her kids are usually pygmy sized, although she is bigger. She has nubian in her, having large ears, and her kid last year came out light brown, with a dorsal stripe, and big ears.
