i think my horse is pregnant?

Question
hello i got a little filly for free and she was out with 3 stallions before i got her is it possibe that she is pregnant because her bags are getting saggy and her belly is starting to drop and get wider and she wont let my stallion get close to her and she is always hungry!  

Answer
Dear Lisa,
        First off yes she's pregnant all right, and second you should probably look her over for wounds because putting 3 stallions in a pasture with one mare could have dramatic effects on her because of all the "Come on's" From the stallions. She may be skittish around stallions because if there where 3 together they where probably fighting all the time for her.
