About a month ago one of my girls stopped laying eggs and eating - she walks around fine and her poop is fine. But we have been feeding her liquid food ever since. Since then another 4 have done the same. Again, they all appear fine and healthy and their poop is fine and solid. They have all been wormed and powdered for mites. They all stay in different coops so have no contact with one another. I've been giving them Harkers for any cocci's for the last two weeks. We live near a bird sanctuary so I'm scared they may have got a new strain of a virus. Our vets haven't got a clue and has said just to 'carry on and hope for the best' as they cannot find anything wrong with the girls they are unable to treat them. We have gone through most illnesses with our chickens over the past 5 years but this has us stumped. They are gradually getting skinnier as time goes by. 4 out of the 5 will still eat treat like sweetcorn and mealworms if given to them but refuse the food and corn they've always had, some of them actually turn their back on the food as if they can't even stand to look at it! Has anyone come across anything like this? Thank you in advance!
