Hi My POL Rhode Rock has got VERY bad breath, but seems fine otherwise. She is eathing absolutely fine - layers pellets and free range - seems perky and eyes are bright and feathers glossy, poo seems fine - not what I would call a chicken that is a bit under the weather. I would not describe the smell as sour, more 'thick' and 'fishy' perhaps. However, I have heard that a chicken with bad breath is not good. Any advise welcome, thanks!
