Most mares maternal instincts will kick in when they have a foal, however maiden mares are definitely more likely to reject or be rough with their foal than seasoned mares. Make sure she is getting proper food for being in foal, and you watch her closely when she gets close to foaling. When do you think she's due? Do you have any pictures of her stomach and udder?
Most mares foal uneventfully, however of course there are risks and her being young could be potentially a problem. I've known people that bred horses young and their's seemed fine. I hope everything goes well for your filly and foal!
