Hi chicken friends, I'm at my wit's end! I posted last week about my chicken Harriet who is losing feathers around her head. To reiterate, she is scratching the area frequently, but other wise is acting fine. She lays an egg most days, is drinking and eating normally, and seems happy (taking dust baths, running around, etc.) We also have no roosters, and our other 4 hens are not exhibiting any symptoms. So, yesterday we took Harriet to a bird vet where she was tested/examined for fleas, ticks, and mites. And NOTHING! The vet also said she otherwise looked very healthy. She then recommended a topical application of olive oil twice a day. She also suggested we give her dry cat food to up her protein intake. BUT . . . because I'm paranoid and because it's breaking my heart to watch Harriet be itchy, I submitted a question to justanswer.com about her, and the vet gave me contrasting information. In part, here's what the online vet said: "Are you sure this vet knows about birds? Olive oil will damage her skin and feathers and may make the itching worse. Cat food is possibly the WORST suggestion for food for a hen. She will be sure to have a calcium deficiency, hyperphosphatemia, hyperproteinenia and kidney failure. Hens DO NOT need extra protein. She should be on a high quality laying hen formula with extra leafy salad greens. The itchy face may indicate a severe sinus or oral cavity infection. The commonest thing is a sinus infection just under the eyes and around the ears. The safest thing to use externally if there are lesions is aloe vera gel after cleansing the area with warm water and a soft cloth. You need to remove the residual olive oil. There are also possibilities such as irritation from insect bites or toxic plants. Washing the area will help these as well. She may need injectable antibiotics, calcium, ibuprofen and many other medications. Act quickly and good luck." (THIS IS ME AGAIN). So, has anybody treated their chickens with olive oil before? This conflicting advice has me very worried!
