male bit my female

[ColleenT]

i put my female in the males cage, and i had thought they bred about 4-5 weeks ago, but she still has an appetite, and no sign of eggs, so i thought i would put her back in with him. he turned to her slowly, then clamped down on her hiney and would not let go. and she was crying out in pain, so i picked him up and he released her, then i put her in her own cage. is this a mating ritual, or a problem? i would like to hear from those who breed a lot...thanks.
