Beeeeeutiful babies (love the little guy's nubbins), and the parents are gorgeous. You are obviously doing everything right with a tricky mountain species. (how are you keeping the humidity high enough in Alberta?)
The female's arabian slipper nose horn cracks me up! (Skeeta broke her's before we got her)
Where in AB are you? (my ex lives in Calgary ... just spinning my mental wheels ... it's only fair to mix up the remaining gene pool since there are no more exports of 3-horns from Tanzania ...)
Good luck and congrats on the husbandry!
