Well I looked inside. I dissected her. There was no fluid. The sagging lump was a pot belly fat gut. She could have been the one that snuck into my worm bag though. Sneaky. I have a lot of pictures, but they might gore some here out so I won't post. Anyhow, her liver was brown instead of bright red and healthy. There were a few red areas but not much. Very unhealthy bird. The rest of my 30 birds are just fine for the most part, but two do have scaly legs - only two. So weird. They got scaly legs while I was gone in the hospital. Trying to fix it now. If I can't I'll end the suffering there too. I hate losing birds.
