Does doing a genetic test involve vets? They don´t know much more than cats´ and dogs´ basic care around here. What do I need to do? I´m quite intrigued, I wish I had more info on these geese, This goose hatched out 3 goslings, one had a darker bill and darker down, but died before it even got out of the nest. The other goose hatched out one gosling. It was back in the winter, and we had a down-pour, the nest got washed down the bank, I washed the eggs off, although I reckoned they´d already be contaminated, and moved the nest nearby to a better place, and she laid one more egg! That must be the one that hatched. I have 3 more geese, I know aren´t CPG, they´re a good mix-up, but could have that gene in them, as they also have the pinky bill. Have tried 6 times to upload photo, no go. Maybe my camera has too many pixels for the system to load. Will have to think of a way around this. Anyway, how do I do a genetic test? Pull a feather out?
