If she just turned 1, I'd hold off. The last thing you need is an immature heifer giving birth to a calf and not knowing what to do. I've been known to hold off breeding for months to allow heifer to mature more (physically and mentally). You could even wait until June to breed her (at 18 months) and go for a spring 2018 calf. Don't know your location, but climate and weather can influence when you breed also.
It would also give you plenty of time to familiarize yourself with what you'll need to know as she grows. If you plan to milk her, you'll be able to prepare yourself to train her for this. There are books and websites on family cows.
I know there are many differing opinions on when to breed; this is just mine.
