I've got a 7 year old leghorn that I believe is dying from old age. "Art" has just been changing over the last month, really ever since the big polar vortex. He just couldn't seem to get warm. He seems a little disoriented at times. His craw is ok, I've given him extra protein, put on heating lamp just so he could warm up, organic feed, he doesn't have worms or lice. Put them all on antibiotics, which I didn't believe would make a difference, but just in case. I've never had one die of old age, they usually get really sick. But this time, I'm thinking he's just old. Anyone else have chickens just as pets been through this? #heartbroken
