I had some Africans but I didn't' get on with them. I found them slightly hysterical.
I got them as a young pair and even though I kept them for over a year whenever I went in to the pen or anywhere near them they ran off or piled into a corner for no reason I could ever work out. I had kept geese before and never had that problem. They might have been different if I had hand raised them from goslings maybe, but no-one will ever sell those or hatching eggs. I had tried for several years before getting that pair.
Afterwards I got a pair of Pilgrim Geese as a replacement, and they have been pleasant and easy going to keep, pretty fair layers, good parents and not aggressive though the gander gets a bit hissy round the nest barrel once they start to lay, especially when I was running two ganders with the flock, once he had gone everything seemed to settle down a lot. I have 5 geese with him and everything they laid has been fertile, though annoyingly I didnt have incubator space to set them all when they were laying a lot.
I currently have one young female Pilgrim which I intend to sell, and there may be more later in the year, depending on how many of the latest hatch I decide to keep.
