Mounting doesn´t mean anything... females will mount, especially if there´s not an available gander. I have one goose that is broody-crazy. I have to watch her, because if she has just one egg left unhatched in her nest, she´ll not come out to look after the ones already hatched, but she´ll leave the gander to look after them, which he does but not as well as the goose, and if I take the egg away from her, she´ll find a stone, or a bit of wood, to sit on! She´s a real terror. I have to fence off the area of her nest to make her leave. Once she´s off, she´s a great mum.I ended up letting her run thru it. Funny thing is that the other goose (presumed to be a gander as it has been seen on multiple occasions mounting the other) eventually sat with her for a long time and stayed several days after she gave up.
What caused you to lose the other one? Could it be that it was actually a goose that got egg-bound?
They look almost the same as chicks. They are all grown now and they love there dam. They swim in it alot and they like to lay in the long grass.
