Hello, my 10 yo daughter was writing this and I am taking over as it is getting a bit ridiculous. The chicken was found unwell on a very hot day and we have hydrated her, kept her inside for a week and given her a week of antibiotics in case it is pneumonia or fowl cholera or similar. She is a lot better but her legs are still not really working. Thus it was a very acute illness and not likely a micronutrient issue, especially as all the other poultry are fine. I also assume that the feed mentioned is different in other countries. My daughter takes animal welfare very seriously and has been vegan her whole life so these comments are taken very personally. I sincerely hope we don't have to get a chicken wheelchair.
