Hi guys, so I own a few ball pythons and all of them switched to f/t right away for me with no problem at all. I purchased 2 more about 4 weeks ago , and I left them alone for about a week before offering food. They were both eating live. So after that week I thought it was alright to offer food. And I did and the citrus took it right away, but my firefly wasn't having it. I put her back and decided I'll try again next week. I did and nothing. Now it's been 3 weeks and she still haven't ate. I know they are picky and they go of feed and I know is sometimes hard to switch the to f/t but this girl just ain't having it. The temp is 90-95, she has a hide, humidity is about 60% so everything is good. I tried the chicken broth thing and nothing.. Any suggestions? Please help

Thank you!
