Vomiting, diarrhoea and inappetence are signs referring to a gastrointestinal problem. It could be due to parasitic infestation, bacterial diseases or viral diseases especially if Jenny is not vaccinated (i.e.: parvovirus). I can also see some black spots on the faeces; that is a worrying sign because it might be digested blood coming from stomach or the first part of the gut. I would suggest to have her checked by your veterinarian as soon as possible. She would probably need further testing (blood test, fecal analysis) and she might need to be hospitalized if she is dehydrated or she continue not to take any food. Good luck and post again on the forum if you need further advices.
