I would leave it alone and wait as if you pull on it and the roots are not well established it may kill the plant. I believe the hardest thing for us gardeners ans would-be-gardeners is our lack of patience. Enjoy what you have and set back and watch nature at work. I copy-pasted this from a serviceberry website there are plenty out there

Propagation:
While serviceberry can be grown from cuttings, it is seldom worth the effort. Seeds are easily collected and germination is usually quite good. Collect ripe berries during July and August and place in a small pail of dry, clean, sifted sand. Crush berries with your hands while mixing with sand. Sift mixture through a window screen, remove larger pieces of fruit. Plant this mixture of seeds and pulp into rows in the nursery, trying to get about 3 seeds per inch (2.5 cm). If you just planted the berry, which has several seeds, the fruit would probably ferment and heat up enough to damage the seeds. Seeds should be planted as soon as possible and will germinate the next spring. Germination is usually less than 50%, but growth is rapid, averaging about 1 foot (30 cm) per year.
