In reply to Sujit's questions about the seedlings being started on a windowsill, I would recommend not transplanting any of them until they go dormant the first time. Give them liquid fertilizer at half the rate recommended on the product, about every three weeks, and keep the pots from getting too hot. To prevent the pots being heated up too much by the sun, you can place a bar of Styrofoam or similar material between the glass and the pots, just as high as the top of the pots. When a pot of bulb seedlings is very crowded, I sometimes get the soil moist enough to hold together (this may be difficult if it contains Perlite, which I never use), then make a hole about the seed pot's size in a larger pot of soil, and try to put the ball from the seed pot into the larger pot without disturbing any roots.
