We have 1 goose and she has been laying for 10 years, we found her in our front lawn. Weeks later her partner showed up. Sadly he pastaway 4 years ago and she morned for over a year, it just broke our hearts. For the last 2 years she has only layer 5 eggs, she used to lay up to 25 to 28 eggs, we are not sure how old she is because she was fully grown when she landed on front lawn.
