Without seeing the degus you can't know whether you are getting healthy stock or not so its all down to trust i suppose, do you trust the breeder in question as she could easily lie to you on here? The only way to tell if degus are healthy is a thorough inspection in person, looking at whether the degu's in question and the rest of her stock are healthy, so a nice shiny coat and eyes and looks like they are in good condition bodywise and also alert and active and they should be friendly. No animal is without its problems at some point and even a healthy animal now could get ill in the future so you must bare that in mind! When you say there is no information do you mean on breeders or degus? As theres a lot of informative degu sites out there now unlike when i first got mine 6 years ago and there was non. Degus make great pets and very friendly and i advise anyone if they have the time and space to go for it as they make very rewarding pets
