Sounds like Roger D. Mucci has this one "covered"...  - at least according to Michael Jacobs !

I wonder if that stud Roger D. Mucci knew this answer.  

My life is complete, now that I know this. 

Thank you sincerely.

Well I was close anyway

Good morning Conrad. Yup, sounds right to me.

Looking forward to getting together later.

A few fillys I knew were a bit older

Now I know...but that still doesn't mean my husband is going to let me adopt a horse

I had to laugh at Fred Griffin's  comment! Thanks for sharing! 

I didn't know a colt could become a mare! 3:)

Hey, I'm a horse person & didn't know that. I was going to say 2.

Thanks Conrad.

Conrad,

I had no idea.  I like horses, and know very little about them. A

I guess I was wrong when I said "What Val Said"

Now I know.  I would of said 3

Thanks for the bit of trivia!

Thanks for the answer. I'll never forget this fact now.

Great info.

Thanks for the answer.

Thank you.

Conrad Allen - well, I was wrong for this one....

Gee, I thought it was when it became an old grey mare.

Okay, now I know. Thanks Conrad.

Thanks for the interesting fact, Conrad.

I appreciate the education Conrad and the "colt" bonus answer also. I wasn't even close.

We learn something new every day!

So if a 2 yr. old filly is bred (a common practice in the racing biz), can the filly have a filly and still be called a filly? 

My guess was at age 2, so I was half wrong. :)

Ooops missed it by a year.

And on the fifth year they are might fine eatin'!

I was off by a year. Great trivia Conrad.
