I second the change in feeder location. Hopefully that helps.
Otherwise....Sometimes it's how you're reheating them as well.
I had to change up my thawing process because of 2 new snakes being pretty picky. Before I would just pop some feeders into water to thaw them out and my snakes would get some extra hydration from eating the damp rats once I heated them up to temp. The new ones however weren't happy with the less smelly rats. So Now they're back to being thawed out/brought to temp in ziplock bags to keep all that rodenty goodness about them. lol
Either way, gorgeous little noodle. She's still looking good so hopefully she'll figure things out while she's still at a good weight and before she starts to loose too much.
