Yes, often times you will see them with flowers at the nursery, still in the small 6 pack packages. As long as they have overwintered, and have a few leaves they can easily begin flowering.

so should i pinch them back... thats what ive heard I should do... or can i let them flower and fruit?

they are albion and fern strawberries

That's up to you. I wouldn't. Strawberries are continuously furring plants, witch means they will grow both foliage as well as fruit at the same time. So I don't see a benefit of doing away with the first berry's.

The idea of pinching the first couple of flowers is to let the plant grow larger before it focuses on producing fruit. a larger plant (green mass) can put more energy into growing larger strawberries.
