My daughter's EE hen's wing was droopy about a week ago. Upon further examination we found a nasty infected lump under her wing. We also found mites while checking her over. We tried to find the site of any injury and found none. We treated her for mites with Ivermectin and gave her three doses of Liquamycin IM and also directly in the infection site. We also soaked her wing with warm water and Epsom salts 3 times. Does anyone have any suggestions on what this is or how to better treat it? We are trying to find a vet who will see her but haven't found one yet. Thank you for any help you can give.
