Hiya,
Yeah, as others have said, it's very unlikely to cause any issues for your BD.
Some people actually feed "feeder lizards" (usually anoles) to their bearded dragons on purpose. Given that it's completely unnecessary, I personally frown on the practice for a multitude of reasons, but when it comes to the health of your dragon at this point, you're probably clear except for the increased risk of parasite load. If you start noticing symptoms of parasites, go to the vet, but otherwise just keep an eye out for said symptoms and you're all good.
A general commentary on the practice of using "Feeder Lizards" though...
This is not directly related to the original post.
The main issue with feeding BDs "feeder lizards" is that they are an excellent vector for disease, even when bought from a supplier as opposed to being wild, as they are closer related to BDs and are more likely to suffer the same pathogens. Since feeder lizards are usually anoles, it's important to note that anoles are generally speaking wild caught despite the species being readily bred. The young are hard and costly to rear, so the industry catches them instead, which stresses the whole "parasite risk" I mentioned earlier. In addition to this, wild caught animals in this case can be a mix of moral right and wrong. For instance, in Texas the Green Anole is native and the Brown Anole is an invasive that is encroaching on it's range, causing behavioral and morphological changes to the native species. I would argue that in that case, gathering the invasive species from the region would be completely acceptable, while you're on more wobbly ground from a conservation stand point gathering the native species (though as far as I am aware the green anole still has a booming population). The final aspect to consider when feeding lizards is the aspect of animal cruelty, as feeding lizards is completely unnecessary for the proper diet of your pet bearded dragon. Furthermore feeder lizards are more likely to die in "ugly" manners to our pets compared to feeder insects. While I am not exactly in the "insects don't feel pain" group many people are, there is the reality the insect nervous systems are less complex.
On a final note, I don't actually know how nutritious feeder lizards are compared to insect?
Anyway, sorry for the semi-unrelated ramble, I just thought that since I was mentioning feeder lizards I might as well follow up with why they aren't commonly recommended for beardie owners. They're more often used for much larger species of predatory lizards, or occasionally very picky snakes.
I'm sure your dragons just find, an I too am impressed with her hunting prowess.
