My experience was by no means a textbook example but when mine were sitting she would get off the nest a couple of time a day to eat and bathe. Often times in the afternoon she would go out to the field and graze a bit. So, being off the nest is not uncommon. Also, her and the gander being protective is very normal. I was hardly able to go in and feed them and put clean water for them until the babies hatched. Ours hatched in about 31 days total so everything may still be o.k.Yes, just the one, sorry I meant to say "baby" above.
She will not let me near the eggs or her. Daddy goose will hardly let me in the yard. I went out this morning and worked on a barrier between the dog yard and where mama goose is, but didn't have a lot of time before work. Will work on it tonight some more and hope for some to hatch. I know that Saturday will be day 34 or 35 of incubation, so I expect if they don't hatch by then, they are not going to.
I am debating checking around to see if anyone has some baby ducks or geese locally that I can buy and let her "adopt" them if none of her remaining eggs hatch.
