The item "Ink Black Chicken Egg" isn't in the JEI and has no texture: It is used in the recipe for this food item (listed in the JEI):
Hi, Lezappen. Thank you for bringing this up to our attention. I looked around and found this issue on github as well. Link to that is in here. The mod pack creator should take a closer look at the pack and remove this one last egg as well. That might take a while. Seeing as you cannot get an ink black chicken or its eggs in any way, shape or form in this pack, I will mark this issue as solved.
