Oh my, not sure what to ask here. Just sad and confused and wanted to share. I'm fairly new new to raising chickens so I'm learning as I go. I bought 6 little chicks, 3 Buff Orpingtons and 3 Road Island Reds, back in Aug. and was so excited to find out 1 Orpington was a rooster. His plumage was so beautiful. Had fun watching him protecting his harem, and hearing him learning to crow in the mornings. Then today I let them all out to free range in a confined area, my rooster walked out and jumped on one of the reds right away, then walked away and keeled over dead. He seemed fine before that, no sign of being sick or fatigued or anything. Could he have had a heart attack or? He was only about 5 months old, seems very strange. My hens seem ok, other than that they sense his absence. Anyone else experience anything like this? I'm at a loss on this one. Too sad! .
