There is a strange HARD bulge on her front. It is yellow-ish & appears to have some dark red (tissue??? meat????) on it. It is a little larger than a quarter. There is no other trauma to the duck. We just noticed it last night. There do not appear to be missing feathers in the region. It does not appear to hurt her at all, I can touch it and she doesn't even seem to notice. I soaked her in warm water last night, cleaned it with peroxide and put Neosporin on it (non-pain killing kind). There are no maggots in the area & it does not smell bad at all. Crested Duck about 1 year old. She's a bit plump, but is not showing a weight gain or loss at this time. She has been sitting on a nest of eggs for a couple of weeks in straw. It's extremely hot in our area. The males were attacking the females, so we removed them from the pen about a month ago. This duck was constantly attacked by the boys & had most of her neck & head feathers pulled out. None of the other ducks have anything like this. She is eating and drinking, swimming and grooming her feathers as normal. Poop is normal. This is our family's favorite duck, any help would be greatly appreciated. We do not have an avian vet in our area. Thank you for any advice.
