Unfertilized Bird Egg Recipes

Hello! It looks like there isn’t any recipes that use the “unfertilized bird egg”, and I was wondering if this was intentional? Maybe it’s a bug on my end? You get them from refrigerators in kitchens… and from what I’ve seen when I checked the wiki/chezzo, this is supposed to be a usable item in various cooking recipes. I’m currently using experimental build 11139. I’ve attached some pictures of what I’m talking about.
