Hello - I have a 1 1/2 year old silkie rooster who has been acting lethargic and off-balance for a few weeks. I did notice just a few mites and treated with Ivomec a couple weeks ago. He's also had baby vitamins and poultry drenge, alternating every other day. He is eating and drinking, although not as enthusiastically. He looks a bit dehydrated. He had some poop stuck to his hind feathers so I gave him a bath today and found 2 large lumps on his side under where the end of the wing lies. They must have been draining at some point because there was very dark, sticky stuff in his feathers. I cannot determine an exact opening (there were several raw spots) but clipped feathers and cleaned the area the best I could. These lumps are very hard, oblong shaped and my best description of size and shape would be like a Guinea egg. He has been isolated but let out to walk around after the other chickens are put away for the evening. This past week has been a better one for him and he is a little more active. He is in the backyard drying from his bath now and is up walking around. We love this guy and any help would be very much appreciated.
