Milk can be retrieved from the Goat to the "north" of the bakery. You will also get Muse.
Eggs can be retrieved from the hen to the "west" of the Seam. You will need a seed to feed the hen before she gives you an egg.
Honey can be retrieved from tracker-jacker hives.

Katniss will appear in your Forest Escape every couple of days. If you chat with her you will get a katniss flower. You will undoubtably need these later.
