So after nothing happened by day 32 I have just opened up all the eggs - all complete duds.

They don't smell rotten or anything. (I have so far never candled, as my chicken eggs are brown shelled and I always felt that I would give all eggs a chance anyway). Might need to re-think that one and build a candling box...
So, this complete and utter failure could be because of one or the other....
1) Gander firing blanks (he is only 1 year old - can they become fertile later?)
2) Gander not quite got his technique right.... I have seen them mating (on the ground) in February a few times but not since... he did look clumsy, but then so does the cockerel. Not seen much action since late winter. Goosey's neck feathers are pristine, suggesting that he is not that regular in his endeavours...
3) Goosey's eggs not right? (They have got poultry grit and wheat at night time, they live in a grassy area that is changed round regularly.
4) Are they just too young?
Welcome suggestions as to what I should do with them - I am keen to breed geese, mainly only for meat with selling breeding stock a longer term aim, as I would need another pair for that anyway. I really love having them around, but they do need to earn their keep...
Should I wait another year and see what happens next year? Change gander (although it seems Pilgrims are not that easy to come by...)? How easily would the girl accept a new man? Different breed of gander - but I would loose the auto-sexing?
These are Pilgrims, and I like them because a) easy to sex offspring and b) not quite that big so would like to continue with them.
