Had to put down one of the niece's RIR RC bantam hens just now. A few weeks back she went down, when we found her she had white urate all over her vent area, partial paralysis, she would keep flopping over on her side would not walk or stand. I was freaked out thinking white diahrrea disease but she got better after just a couple of days, and showed no other signs (comb and wattles/face bright and clear, eyes good, breathing perfect, appetite, etc.). None of the other birds got sick. She was a nice little hen and closest to weight and also probably the best keel so decided to try her again. I went out to check on the birds before bedtime and there she was- exact same position, same white urates, everything else fine.
When I dissected her saw that her abdomen area looked almost bruised inside (as I was looking from the outside). It was greenish in color, but not like a bruise I had ever seen before. When I looked inside, a part of what looked like fat in her intestine looked strange so I opened it and out squirts bright green fluid. It had stained the inside of the abdomen wall, very strange. anyone ever seen anything like this before?
Too bad to lose a good productive nice little hen that the kids love, would at least like some answers... hoping some of the knowledgeable folks here can help.
