My Serama Rooster Zeus is the happiest little guy runs around and crows non stop. Yesterday he came out and his crow sounded like it was real hoarse almost scratchy. Does this have anything to do with puberty/growing into a man thing or is he sick? He is just as energetic as always but his crow is not the same. Any suggestions or ideas would be great. We are worried and my wife is distraught about this. Zeus was born the first week of August.
