Heart or lungs...lack of oxygenI found a buff orp. dead on Friday could have happened anytime between 730 am and 230 in the afternoon. Just over a year old. No sign of trauma. She was in the run, I let them out and left for work. They can come and go from coop and run during the day. Her comb was half purple. Would the comb turn purple before or after she died?? Just wondering if it was a heart problem?
