....my large black Nero hen has recovered well. Luckily I discovered what was changing her behaviour and causing very wet poo in time - although it was an "emergency" op. She was operated on the week before Christmas, and as soon as she was sewn up (and sprayed with antiseptic silver - a very festive touch!!) she was up and eating. Having said that, I kept her in and she did the most horrible smelly black fibrous "do" the next day. ( I discovered some couch grass just poking through the edge of their large run......and assume this must have been responsible as she must have got hold of it - as all "greens" given to the girls are chopped up). She now seems to drink more than before and although her poos do contain solids, they remain much much wetter than normal. The vet saw her a week after the op, but this "after effect" wasn't really apparent at that point. Does anyone have experience of this op.....could it be kidney damage? She seems well in herself, eating (and she is head of my flock of 8 girls) and she quickly reestablished her position at the top of the pecking order.
