WE have found that it is better to bring the goslings up ourselves, so far Mother Goose has been a bit slapdash, and we have lost all the goslings when left with her... also watch out for crows and if you have them gulls or magpies, as well as buzzards…
You will need ramps for the little ones, and I am currently re-filling the water containers for our two (about 6 weeks old or thereabouts) at least four to five times. It is dog's water bowl, but they just tip it up. They are still in a playpen (moved once a day) with a shade cover on top.
