Today we found one of our little japanese bantam hens with a FAT tick on the side of her face. That side of her face is swollen and so were both of her tiny wattles. She was not her little feisty self. She was subdued and easy to catch. I removed the tick and applied some anitbacterial gel. She ate some bread but I haven't seen her drink anything. There is an indentation where the tick was . I isolated her and gave her some avian 2000 in her water. Could she have an infection? Why is her face swollen? Any ideas and advice would be most appreciated!!!!!
