She's in a herb bed outside our kitchen window facing south and although there is some shade from the plants if we have no rain they will soon wilt. We could build some sort of shade shelter but we're worried about scaring her away. Any thoughts? Can I water the herb bed to at least keep the plants alive?
This is where well meaning folk like yourself are stuck between the devil and deep blue sea. Sadly you can't do anything, it is illegal to disturb nests, and while I feel for you not only for the welfare of the mallard family, but also the herbs as well, that really is it.
