Generally bunching onions do very well when transplanted. The only time it is best to sow directly is when growing for a young harvest. Start winter harvest bunching onion seeds indoors during the fall. Warmer soil temperatures can help encourage strong germination (50-60 F is suitable). Sow 2-4 seeds together and cover lightly with soil. You may need to transplant 2-3 times depending on how quickly they grow and your preferred transplanting time. For a fall harvest (recommended), transplant into their final location in the spring.
