How long does it take for the smell to be there? I got a brown leghorn on Saturday and notice today (Monday) that one side of her face seems swollen and she keeps that eye mostly closed. The eye is a little watery and that nostril is running. Not sure if its coryza but I have moved her to the basement until I know what it is and what to do.
Check the inside of her mouth for pus.
