Hey. I haven't try it but I suppose You need high level of foraging. And you can forage it in woods or with command "Gather flora", if You red Flora Fieldguide. Also You need to remember that many stuff You can't find during winter (from november till march). Hope it help a but.

Maybe You can help me if you gather some animals. Where I can find rabbits. My base is near Riverside on Farm. I'm playing in Sandbox mode. I'm confused with thisnew build don't know where to look on them. Zomboid map doesn't show any cornfields. ( i heared that Ican find it there).
Thanks.
