I have had geese forever, however I have just started really learning about them with Emilee. She was the only egg that hatched out of 8 and is imprinted. That is a whole nother can of worms, however yes, you can teach them things. Emilee was hatched June 10th and although young says "Ut Oh" when its time to get her diapers on and thats the only time she does it. I never taught her, I just say Ut Oh while we are fighting to do it. She will stay in an area while I mow or do my thing. Allot of it is like potty training a child, you don't potty train them, you simply learn when to stop giving them water so they don't wet the bed. Same with geese, it takes some conditioning on your part as well to get the over all effect.
