I have 4 turkeys. 2 Bourbon reds, 2 Chocolates. 1 chocolate developed a swollen cheek 2 months ago. The 2nd choc. developed same several weeks later. 1st Choc responded to Tetracycline in drinking water and now looks normal. 2nd choc did not respond and swelling has grown larger than a large grape. Otherwise, all run, jump, eat, etc. What do I do?
