I saw your other thread, that comb must be painful! This may be why she's not wanting to eat much. Is she willingly drinking? Hydration is very important.No egg has tried to pass. She wants little to do with food.
I would say direct dose her with poultry nutri-drench, but....with that comb, handling her may just hurt more than help.
Is she a daily layer? My W Leghorn is a laying machine! Stress from it all may delay her for a day or two hopefully she will get back to normal in the laying department.
