Hello, I have a silkie chicken 4 mths old, and today have noticed the exact same thing. The smell is putrid, seems to be from her ears. She doesn't seem to have a big appetite like the others either. I've treated their water with sulpha3 (an antibiotic), bought from the pet shop, so hears hoping she'll come good. Also gave her vitamin soaked bread, as she loves bread, but nope, not eating it today! Her eyes are almost like she's blind, very watery, walks around so slowly and seems to sleep a lot. I would also like some suggestions please!
Thanks
