I've posted a few times about a sick hen (sorry!), and I'm at a loss as to what to do with her. She's been like a zombie for over a week - she won't eat or drink (drinks a little when I make her), has her feathers fluffed up and mostly just stands or sits ion the corner. I suspect it's mareks, because I had a rooster that tested positive, though this one has been vaccinated. Should I force feed her? I've only managed to shove a little bit of cheese and some tomato in her beak, and it was a real struggle. I'm giving her water with hypericum and vitamin B complex, but there's no improvement at all.
