I bought "Mom" as a male, and when he arrived I found out he was a she!!! so It was kinda cool, I gotta female for a male price.....anyway, she was around 5 1/2 feet when I got her a year ago, I am not sure how old she was because she had changed hands a few times, I got her up to six feet with good body weight by this season, and I threw a male in with her....boom she ovulated....I am guessing that she is 3 -1/2 years old.....I will bulk her up this year and see if she is willing to go next year
