My ducks do forge , eat bugs , grass, weeds ect
But their main feed is crumble
They are use to me providing it
As well as putting them in at night in a secure building
The problem is moms stop at 3-5 weeks and force them on their own
In that 3-5 weeks she teaches them how to swim , eat ...
I have to agree
Once a duckling is domesticated it’s very hard for them to become wild
They learn how to do this in the wind be their parents
Without guidance they won’t know
They will be use to having security from predators. Feed in a bowl
Please just find them homes
