My polish chick was doing very well, so after a few weeks of isolation I put her in with some young seramas. This went fine for a couple of weeks until one of my seramas decided it was a cockerel and became aggressive. It was only picking a few of her back feathers at first so I added an extra bucket and some perches for her to get away from him. The problem seemed to stop but then I came out to feed them one day and all of her back and crest feathers were GONE! Her left eye was swollen shut too. I took her out and put her in isolation in one of my brooders. It's been over a week and she hasn't shown any improvement, in fact she looks WORSE! Her eye is still swollen and will hardly open and a fleshy lump developed on her head. Occasionally it will scab over and I'll wash it really good with warm water and anti bacterial soap and the scab will peel off. I can see little feathers trying to sprout but they don't seem to be growing. I peeled the scabs from her back today and the flesh underneath looked very pink and healthy and the feathers were starting to grow back. I'm very worried about her head and her eye though. She eats, drinks and poops normal and has plenty of energy. Her good eye is bright and alert. I've been giving her duramycin and electrolyes in her water everyday since this happened and have been cleaning out her eye and cleaning her wounds and putting neosporin on them everyday. Her head and eye just don't seem to be getting better. Any advice or suggestions? Anyone have any problems like this before? None of my other birds are sick. Is this just a REALLY BAD case of being picked on? If so how long till she shows improvement? Here are some pictures of her head.
