Realizing this is an old post, but very helpful for us newbies. A few weeks ago, I had a similar issue with ducks, I tried to move the nest, that didn’t work- in the end I incubated the eggs - I have doubled my flock -10 ducklings…. I was also worried they would fight. Today, I have mother and daughter geese each sitting on their own nest - only the sitting started 3-4 days appart- wish me luck - I am hopeful the gander will adopt the ducklings, the geese will be patient to lay both sets of eggs and raise the lot. Then figure out what to do with all extended family
