hey Don - I measured him last month and he was 33.75". The billy next to him is 2 years younger and measured 30.25". This 3 year old is named "Wild Bill", and is bottle raised. He is the fastest growing Ibex we've had. I really think in the next 18 months he will be 40", if he continues the pace he is on. Since measuring him last month he's already put on about an inch.
The billy in the second picture I haven't measured in a while....he's also bottle raised. He was from semen out of a Persian billy from the Florida Mt's in New Mexico.
