I have a cochin rooster that is just under a year old..i went to his pen today and noticed his neck from the underneath of his beak to his crop is competely swollen!!!! Even around his eyes is swollen.. I have never seen this before. At first i thought it was sour crop or something but when i lightly squeeze it feels like a whole lot of air bubbles packed in there.. I havent noticed any others looking this way..hes in the house but seems like his breathing is getting worse.. Does anyone have any idea or experienced anything like this before??? He is my baby and i cannot lose my guy!!!! Please any ideas at all???
