Your goosies are so beautiful! So happy for you. Makes me wish I knew my Francie when she was a young girl! Francie likes nice tender lettuce (no iceberg) and just about all veggies and fruits. She especially likes juicy melons like cantaloupe. I feed her Mazuri waterfowl maintenance also. Not sure of any other feeds, but I'm sure there are many good ones out there. I also give brewers yeast for niacin. There are lots of good books available about geese. I have one by Chris Ashton that's been helpful. Also, you can't get better advice than on this website with all the caring goose people. Best wishes.
