Is she thick? Putting netting over to stop gulls but also likely to trap small birds who wont just fly to the corner gap
the ducklings escaped not by flying away bit by walking off site didn't it? How is the netting stopping them from getting out under the gate again.
The netting will cause stress to the adult. No "expert" would say to put netting on. Quite the opposite they are very anti netting as it just gets birds trapped. She's absolutely getting me mad with her total lack of care for these wild animals.
Does she even know ow that mallards have so many ducklings gs because nature ie gulls do take a few. But that is precisely why they have large broods. She is messing with nature and the place will be over run with too many ducks if she keeps doing this year after year which I know for a fact the local WT do not want. Honestly I'm so close to messaging her saying she's doing more harm than good. She's got no idea yet makes out what a do gooder she is and wanting a pat on the back.
