my GBB has its old exuvium stuck in the Chelicerae part. he/she cant get it off. i tried to mist it so it would soften but no luck its still stuck. tried helping it by pulling it off but still its stuck. i feel that i even made it worse by trying to softly pull it because i think it injured the Chela. what else can i do? i think this could also cause death. i dont want to get to that point. so if anyone there could please share their experiences or advice i would pretty much appreciate it. thanks!
