I noticed him sneezing and having a weird voice when he crows ( sore throat possibly?). Also his noises when he's in danger sound muffled. How do I treat him? My hen had it first and I think it spread. She's occasionally sick at this time in the year and recovers nicely. This is my roosters first time being sick, right now i gave him penicillin antibiotics in his water. Is that any good? What are your recommendations?
