We're really worried about our hen (approx 14 months old, ex BAT). She has gone from being a lively, enthusiastic, greedy hen to being lethargic, dopey and she has virtually stopped eating although she is still drinking a lot. We took her to the vet today and he gave her an anti-biotic injection, but said we just need to give her some grit/oyster shell and feel her probiotic yoghurt. We have bought her Yeo Valley raspberry probiotic yoghurt and Oyster shell and tried to interest her in this both by itself and mixed with layers mash. We have also given her mashed banana. She has eaten a few pecks of the yoghurt/mash mix, but nothing else except some grass. Can anyone give us any advice on what to do next? And is it possible to force-feed hens humanely, as we really want to get some nutrition into her? We're worried she hasn't got long if she doesn't eat...
