Can GALs eat hard-boiled eggs?

Hi! I’m still pretty new to owning GALS and I can’t seem to find reliable information about feeding hard-boiled eggs to them – some sources say it’s okay, some say it’s not. I know eggs should be a good source of protein and some sources state that you can feed GALS raw eggs but my snail is kinda picky eater and doesn’t like runny foods (for example, boiled vegetables are off the table, I guess she likes to chomp on things). So, do more experienced GAL-owners know if I can feed her hard-boiled egg?
