That is definitely not a Siberian ibex, if I’ve ever seen one… This appears to be just another game farm Caprine “mutt”, if you will. It might have some? Siberian ibex in it, but it also has a lot of other things (including a lot of domestic goat)…
Thank you for the correction and clarification. I didn't really think this would be a hybrid/mix (never seen an actual Siberian Ibex before). I updated the title.
For the record, they were signed as Siberian Ibex.
