Protect your new seedlings with this...

A Baby Net; available at Big C, Tesco, or Carefour for about ฿250. Colin lost 1 or 2 plants just after they sprouted, to birds. Wait until your plants out-grow the net and they should be ready to face nature.
Just after I wrote the above; a brown, thumbnail sized moth got under my net and decapitated my latest sprout; the one that came up this morning.
These damn moths fly fast and erratic and it went under as I replaced the net and I missed seeing it. Nuts!
