It's SO FRUSTRATING when these silly snakes won't eat.

I've had a female yellowbelly, barely breeding size, for about 7 months now. She hasn't eating for me once. The old owner said they had cooled her for breeding, but decided to go in a different direction. She joined my rack of snakes, who were also cooling for breeding, and was paired with one of my males. They locked many times, then about halfway through the season, she's rejected him every single time. I warmed up the racks as scheduled, all my females who laid are eating (one very sporadically, but she has taken one meal since laying), and she is the only female holding out. I can't for the life of me get her to eat. She was on F/T when I got her, but I'm thinking I might be trying a live here soon. She, however, has shown no interest in even the smell of a rat.

I have a very large Pastel male who ate regularly when I first got him, but has not eating for months now. He stopped eating in the middle of breeding season (he wasn't one of my breeders), and hasn't snapped out of it yet. He has some WEIRD shed issues, no matter how high the humidity is, he always seems to have stuck shed. He also has got one heck of an attitude, never strikes, but hisses if you even walk in the room. He shows interest in the scent of a rat, but won't eat. I'm also going to try a live with him here soon.

All the other holdouts have started eating, including another male who had gone a long time without eating. Neither are looking skinny, although the pastel has thinned a bit. Does anyone have ANY advice for me? I've tried Nutribac in the water, I've tried heating up the rat with a hair dryer, I've tried water thawing and drying them then warming, I've tried air drying them and heating them, I'm out of ideas other than a live, which is really the last thing I wanted to do!

I know they can go a long time without eating. An Ivory I got went 9 months without eating before he finally started eating with the aid of Nutribac in his water for a couple weeks. I just feel like 7 months for a female who is only weighing in at about 1500g and a male who has shedding issues, the extra stress of not eating could be bad...

Sorry for the long winded post, any advice?
