Rachel Alexandra and her first foal are ''doing well'' a day after the 2009 Horse of the Year gave birth to a bay colt.
Stonestreet Farm says on its website Monday that the focus will be on allowing Rachel and her foal to adjust to one another, and farm manager Gary Megibben adds that Rachel is ''a natural mother who took to the colt immediately.''
The 125-pound colt with a star was sired by two-time Horse of the Year Curlin.
Megibben says the bay colt was born Sunday near Lexington, Ky. and took his first steps about 90 minutes after birth.
Owner Barbara Banke says she and co-owner Hal McCormick are looking forward to watching the colt develop.
The 6-year-old Rachel Alexandra was the first filly in 85 years to win the Preakness when she accomplished it in 2009. She finished with 13 wins and five second-place finishes in 19 starts. She will be bred to Bernardini this year.
Curlin, who was Horse of the Year in 2007 and 2008, stands at Lane's End Farm.
