Hi and welcome to the club! I have a girl that does nothing but try and bite me as soon as I open the lid! Shes just a big grump but none of my others seem to be a problem. When i want to move her out of her tub for cleaning i usually just bump her side and she calms down (only a bit though) since she knows its not food. But she is still really defensive. I make it a practice to bump all of my snakes on the side to calm them before picking them up. It seems to kill their feeding response. Also to keep mine on the scale i use a tupperware container and lid . Just put the container and lid on the scale and zero it out. Then put the snake in the container pop on the lid and theres your weight.
