We have caught geese and are now waiting for two hours, so the birds can get rid of all the shit in their digestive tract. If we would not wait, ri9nging and sexing becomes a very dirty job. But in this period, i realize that we have to few colour rings for this amount of geese. So Janwillem is put to a job to bend more rings. In hot water the engraved plates become soft and he can bend them in a round shape. In cold water that shape is retained.
