I have an EE that is less than 6 months old, not laying yet. We noticed a couple of weeks ago that she has a lump on her back, near her wing. We haven't been able to catch her until today when she was allowing us to pick her up. The picture is what we found on her back. We put her in a cage on our porch with plenty of water and food, which she gladly accepted. My question is, should I open this up and see what comes out? The lump extends under what we can see. I have the tools (I am a nurse practitioner) including 18g, 22g, 28g needles, scalpels, etc.) readily available.
