She looks to be in rough shape, eyes appear to be closed, and the container/fake branch looks dirty. Poor thing.
I have not had good experiences with reptile shows in our area.. It seems some of the larger shows have great breeder presence, and I hope one day to attend, but the ones I have encountered have reptiles in poor conditions. If there are any chams, they have been in poor health. My first chameleon was purchased at a dingy show, he was sick, and lasted a rough 3 weeks of vet bills before passing. (RIP Gus)
