I've had this messor queen for about 4 months and her eggs don't go pass the well,EGG stage they just shrivel up and dry...and then the queen starts the process all over and over again.
The only thing i have tried to prevent this was make it more moist in the test tube i thought maybe the cotton wasn't receiving enough moisture so it pushed it in a little bit more in,later...same result.
I really have no idea what the matter is,here are some pictures(bad quality i hope they do):
