Last Years Leeks

I sowed a row of leeks last year in my cold frame, however the soil wasn't great, and they hardly came up at all - in fact, they were there so long, that the label washed off, and I forgot what they were.  They looked a little bit like weedy spring onions. 

Anyway, I left them there, and roll forward to this year, and they look like quite healthy, but small, leeks (which is obviously what they are!)  They are a bit bigger than the spring onions you see in the shops.

So, my question is, can I transplant them for growing on this year?  They are almost a year old - will they come to anyting, or are they just going to bolt?

Cheers in advance

Sorry, but I think they are certain to bolt, and probably sooner rather than later. 

If they go to seed, it will be premature (for me!)

I am eating loads of last year's leeks too. They are lovely whether be fat or thin    They are great in soup, casseroles and the thin ones I like just wilted a bit in boiling water and then onto the hot griddle pan 

I think leek and potato soup is very under-rated. At its most basic it's fab but with the addition of bay leaves, bit of cream and white wine, it's up there with the greats
