Please can someone help me sec my gorgeous bluebell???

That's a lot of comb for an apparently young bird, but it's impossible to make a solid gender guess from that picture.

And how old is (s)he?

 

If it's not fully feathered but has that much comb and wattle development then yes, your gorgeous Bluebell is a little cockerel.

 

The exact same thing happened to us the first time we hatched eggs. It's a bit heartbreaking, especially if you can't keep any (like us).
