Help ! I went away for a couple of days to come home to find one of my lovely little bantam hens looking AWFUL! Her comb looked all bloody and her eye wouldn't open.. I originally thought it might have been an attack from another hen. She's super puffed up but seems to be eating and drinking ok. She's on the nest at the moment but has been there for quite a while. I also noticed some tiny, tiny white insects crawling on her head through the scabs. What is going on ?! Help !! What should I do ? I also have a mama hen with 5 chicks, 1 laying hen and two new 5 week old standard size chicks. Everyone normally gets along fine so I don't know is it mites ? An attack ? Disease ? She's normally so beautiful I would hate for anything to happen to her ! Any advice would be great !
