I need some help... I've been trying to get my burms to switch to frozen but they just won't accept them. I've tried teasing them, scenting them with live, braining them, even tried feeding pre killed but they won't go for it they just come over as if they were going to strike then they back off. But as soon as I put a live one in POW they take it right away. Are there any other tricks I can use to get them to switch over. Any help would be appreciated.
