Hello! So I have a hen, I noticed about 2 weeks ago that her face was swelling. I guessed it was coryza, so I separated her from the flock and gave her the prescribed medication, along with the rest of the flock. I gave her the medicine for 7 days, as the packet said. It has been 12 days now since I started giving her medicine and her face did not stop swelling. It was smaller compared to before. She is still as lively like before, only the swelling face is the problem. Should I give her more medication? Thank you so much
