I was able to finally figure out the eggs that were not able to be cooked.

"PrimalItemConsumable_Egg_XSmall_RR_Medieval_C"
"PrimalItemConsumable_Egg_Large_RR_Medieval_C"
"PrimalItemConsumable_Egg_Medium_RR_Medieval_C"
"PrimalItemConsumable_Egg_Special_RR_Medieval_C"
"PrimalItemConsumable_Egg_XtraLarge_RR_Medieval_C"
"PrimalItemConsumable_Egg_Small_RR_Medieval_C"

Now I was able to make the eggs cook-able in the kitchen grill by using this command;

ConfigOverrideItemCraftingCosts=(ItemClassString="PrimalItemConsumable_Egg_XSmall_RR_Medieval_C",BaseCraftingResourceRequirements=((ResourceItemTypeString="PrimalItemConsumable_RawMeat_C",BaseResourceRequirement=10.0,bCraftingRequireExactResourceType=false)))


and so on for the remainder of the eggs. It was killing my soul that I couldn't cook the eggs lol!
