Just put the other eggs under her & she was fine,I’ve raised Pebbles from 1day old so she sees me as her mummy lol.....,she does have a small ramp going into her house will the babies be ok or should I move them to the other little house which is on the floor?
Just monitor her and the babies closely, some ducks adopt well, some don't... ducks more than chickens bond to the ducklings well before hatch, so that's why they're harder to slip pipping eggs or hatched ducklings under...
I would block her and the babies in for a day or 2, until they're all hatched and on their feet... then make sure they can get back in easy, or move then, if needed...
