Congratulations on the new foal!  It is wonderful that a 23 year old mare
can still have babies with no problems.

Just wondering, have all her babies been born at this time of year?  Late
in the winter or in very early spring?  I just read in the book "THE
REPRODUCTIVE BIOLOGY OF THE MARE" by O.J.Ginther, that several studies have
shown that mares who foal in winter or early spring on average have longer
gestation lengths than mares bred to foal in the summer!  It appears that
mares are able to make a limited adjustment in gestation length such that
foals tend to be born in the apring!  My mare Stella had her two last foals
in mid summer (around the 1st of July) and she foaled two weeks before her
"due" date each time! (I don't know what her record was for the first
four...Anita?).  I wonder if a mare who foaled "early" in mid summer each
time would foal "late" if she were bred to have her foal in late winter? Or
vise versa?  Or does each mare do it on her own time table each time?

Jean in Fairbanks, Alaska, where it will be sunny and +25 today! Fjords are
starting to shed but have a lot of hair to get rid of.
