Hi Tori...you've done a very nice thing taking in 2 sick beardies. I do hope you can find homes for them....it will not be too hard with the healthier one but the sickly one may be a real challenge. It might be helpful to take her out in the sun if you don't already do so. Just set her in the grass and let her soak up the natural sun. That can help strengthen her bones and possibly improve her condition. It would be good to add a good reptile vitamin to the slurry, but just twice a week and only just a pinch. Herptivite is a good brand,
I hope you can find good homes for them, I wish the best possible outcome.
