Just got a 6mo.old Brahma hen, she has been with roosters so this problem could be caused from mating, her head is swollen looks and feels like theres fluid in it and feathers are missing ,she's not bald but there are feathers missing. What i want to know is there anything i can do for here or just wait and see if it goes down by itself? I put spray iodine on it and i also have bluekote. thanks for any information.
