My C Ashton book "Domestic geese" has got a weight loss table for incubation in it. The starting weight for the Pilgrim example is 200g.
Just weighed my three eggs so far, they come in at 110g, 120g and 123g - these are 1 yo birds, so wouldn't be rearing breeding stock from them anyway.
Is the success rate dependent on the weight of the egg, or will these just be smaller goslings when hatched?
Will the weight of eggs go up this year as the breeding period gets going properly? And should I wait until heavier eggs appear - or won't they this year?
