I am trying to breed veiled chameleons. I place my female into my males cage and he is acting agressive toward her. He head butts her hard and this last time he tried to bite her. Is this normal? I know the female will hiss and bite when she does not want to but what is the male doing? He is show the correct colors but is acting not normal. What should I do? Am I doing something wrong? I know he wants to breed. He is going crazy over her.
