@Dottie the Chicken, could you please stop tagging me on the thread Farm chatter, please?
It's nothing personal, I would like to try to stay off random ramblings as much as I can, once again, nothing personal.
In general, a puffed up bird for no other reason can be a sign of illness, but is this chicken outdoors? Is she cold? Is it a hen? Is she broody? I would suggest an avain vet visit.
