Hi, I got a TB mare earlier this year and she and I bonded really great. She follows me everywhere and lays her head on me. Anyway, she foaled early Thursday morning and and up until today she still followed me and nuzzled me. But today, she won't even let me pet her. Until now, she would get between my husband and the colt and push the colt to me. So is she just in a bad mood? She would just stand there and let me groom her and I tried to groom her, and she wouldn't let me get the brushes near her. What's up?
