Hello. I am hatching some chicken eggs in my classroom. Today is day 6 of incubation. I noticed today that one of the eggs has someting strange on the shell. It looks like spores or something. There are three patches of it on the egg. Each patch is made up of a bunch of little spheres. I've never seen this happen before. Does anybody have any idea what this could be? Should I remove the egg from the incubator? Any help would be appreciated. Thanks!!
