Axel is gone, euthanized. He was just shrinking in on himself, refused to eat or drink. I did dropper water into his beak quite a few times so he didn't become dehydrated, made him scrambled eggs which he ate the first time, then refused after that. He just kept getting weaker and weaker, comb turning black, etc. After he was gone, I examined his body, though I did not do a necropsy. I could find nothing physical that told me what happened with him. No symptoms other than lethargy and loss of appetite.
It will remain a mystery, I guess. I hate mysteries. Usually, if an early death happens, it happens during or as the molting bird begins growing feathers back. The molt seems to bring internal issues to the surface. RIP, handsome little guy.
Now, we have 23 birds, 11 large fowl and 12 bantams. Hard to believe that once upon a time, we had 55 birds, only one of those a bantam at the time.
