My mother kept geese and always floated them in warm water quickly for about three days before they hatched, can only guess its to do with humidity and of course you can tell how many are alive and kicking. Looks like we have a potential 9 out of 12, but I,m not going to count my goslings before they hatch.
Also she always removed the eggs when they were hatching and finished them off over the rayburn and then fed them on oat and egg pellets. Does anyone know if this is the best way forward or do I leave the goose to get on with it and hope the gander does not eat them
