How long have you had your female norway? Im waiting for mine to pop and it should around wed. Im not sure if they are preggo or just fat lol I have 3 that are breeding size. I have tracked her weight from 8-2 she went from 220 to 299 tonight. The others I havent tracked that closely.
I can't find it now but I did read somewhere that if they are to be feeders do not feed them food or treats with red dye, so I just avoid the dye all together now.
