Hi,
I planted some japanese onions last winter & after a few month of not doing much, They are starting to swell. My concern is that they look a bit shallow, is it a good idea to earth them up a bit?

Also would birds do damage to them?

No and No.

The bulbs grow above the ground and if the birds haven't moved them for you by now, I doubt they will.

Thanks
I was getting concerned as when I went to check on it & weed the birds were there straight away as soon as I had my back turned

They'd be after what you'd disturbed in the soil when weeding. The onions would be too well rooted for them to move.

They're very good at re-postioning the sets when you first put them in though.
