Help with mod to allow dairy and eggs for Wurt please

[KittyBiscuits]

Hello,

I am unsure of how to tackle this as I am still inexperienced with LUA despite having made a couple mods here and there, though I did have help from a friend. I want to make Wurt able to eat eggs, dairy. I understand that the game organises food into food groups. I don't want to create a new food group because it will probably conflict with Wilgfrid being able to eat them? Unless food can have more than 1 foodgroup tag? Is there a function that will allow Wurt to eat certain foods by referencing their script.lua files? e.g 'If egg, tallbird egg etc, allow?" kind of thing? I'd really appreciate any help you can offer

I even made cover art because I thought it was gonna be simple to do T_T
