Collard doves nesting on our balcony

Hi,

5 weeks ago my partner and I put a small bird table on our juliet balcony. This was due to a blackbird that had nested in an open vent above our second story flat.

We had 2 collard doves regularly visit and our recently purchased onion planter has turned into their nest with 2 beautiful eggs.

They're very comfortable with us. Our dialy routine doesn't faze them at all. When they change at dusk and dawn sometimes we manage to get some seeds back on the table before they eat them up. Although usually they're together for this.

What care can we take to not disturb the young once hatched? Stop with the seeds? Try to be quiter? Any advice at all really. We've grown attached to Poppet and Peter.
