I find this happens a lot. A seedling will sprout, but the shell remains fixed onto the leaves, inhibiting them from growing. If this happens while they're under the hydration dome, I'm usually able to carefully pull them off, as they're moist enough. But once I've pulled them out from the dome, they dry hard and pulling them off usually results in pulling the head of the plant off.
Will they all ultimately fall off on their own? Is this just one of the casualties of Mother Nature, and I should just plant more so enough survive?
