I have 4 Black Rock chickens which I bought 3 years ago. They were really good layers, pretty much giving me 4 eggs a day until around October last year. I now have on average, 6/8 a week. Over the last 3 weeks they hardly eat anything and have become a lot quieter. Today I noticed one of them has stayed inside all day and after just checking on her she looks really poorly
Her wattle leans to one side and is turning black, when I tried to move her she looked unsteady and lethargic. The other 3 seem fine with bright red wattles and are full of beans, although no eggs today!
Does anyone know what could be the matter with her?
