I am afraid that this is not a simple problem that can be "cured" with Q-tips and a little warm water.

Never, never, never, and I repeat never buy chicks, hatching eggs, or breeder fowl from a hatchery or a breeding farm that does not have a current as well as past years pullorum free certificates on hand, and insist on either seeing the certificates or having copies of the certificates mailed, e-mailed, or FAX-ed to you before any money, eggs, or birds change hands. Also don't "adopt" chickens whose health history in reguards to pollorum disease is unknown. There is a quick and easy test for pollorum but it isn't cheap.
PS: there is nothing that will "cure" pullorum disease. Any chicken that survives pullorum disease in the short term will remain a pullorum Marry or pullorum disease carrier for the rest of that chicken's life. Count on it!
