My goose has been sitting on her eggs now for 31 days. They are too thick to candle, and I don't like to take them out from under her to keep doing this - I don't want to disturb them. Four of the eggs are really heavy, one is really light. I'm beginning to think that maybe none of them is viable as there is no pipping on any of them. Does anyone have any advice about how much longer I should leave them before I take them away? She's doing ok, but has lost some weight, and I don't want her to become ill - but don't want to throw away viable eggs!
