I agree with Woodmort and ARose4Heaven
Disease can happen anywhere, but rare if chickens are housed well, pastured well, new birds quarantined, etc.
Stay away from this section unless there is a problem you need help with.
I've lost birds but never an adult and always an individual. I would have investigated if it had been multiples. Someone on BYC said that if dogs died at the rate chickens do, there wouldn't be very many dog owners.
You mentioned respiration issues a couple of times. IMO that is almost always a result of poor coop ventilation. I have no scientific evidence but, knowing lots of backyard pet chicken owners, I suspect it is the result of trying to keep the chickens warm in winter which again IMO is not the thing to be concerned about unless you live in MI, WY, AK or somewhere like that.
