I have a Call Drake I believe has a sinus infection, as he has a swollen cheek, although it is soft and nothing came out of his nares when I massaged it. I just noticed it this morning, and have him inside as it is in the 20's-30's F. I have him taking baths/drinking ACV water, but am wondering, if I need antibiotics, can I get something from Rural King/TSC or similar? No poultry vets around. Lump is on his right side, and the two spots below the nares are actually bill coloring, not discharge. So far I haven't seen any.
