Yes our Pilgrim pair has turned out to be very expensive.... goosey girl laid a good number of eggs when 1yo, but all were infertile as boyo hadn't worked out the important bit... goosey then died that summer... we got another, most likely Brecon Buff type goosey with three of her offspring from someone else on TAS, we ate the youngsters and kept the girl in with the boy... they liked each other, and hey presto she laid a good number off eggs and we managed to hatch three in the incubator (out of 7), and a hen hatched another (and I managed to take it off before the hen killed it...) and then goosey hatched two herself (but both died a few weeks in, I think she wasn't that keen on her offspring after all...). We have just dispatched the 4 goslings, but weights were not that good - but these are Brecon Buff x Pilgrim, so were never going to be big.
Our problems with the incubator has also been the "dead in shell" just before hatching...
As we are not set up to deal with many more than 4 to 5 goslings per year I think we will do this pair another year and then I would like to try and get an Embden pair, just to get some size... A couple of Muscovies for broodies is also an idea, but we need to work on housing/runs etc for next year first.
Have you looked into getting day-olds, but I know they are difficult to come by. I have been on a farm tour at Andrew Whitley's place (
www.breadmatters.com), and one of his current strategies of grazing management is having a flock of geese - bought in as eggs (as he needs them organic) and then hatched and reared organically as table birds for Xmas. He also has quite a few problems with hatching - and I understand that all breeds of geese are problematic wrt hatching...
I now run the incubator totally dry until lock-down, and then spray the eggs with warm water.
Not sure this helps much... we have found that the rearing is actually quite easy, but the hatching is the difficult part.
