I urgently need your advice... One of my yearling black swans is showing signs of a reddish diarrhea and with a jelly appearance, something I had never seen before. The other one is showing a sort of whitish diarrhea. They both yesterday didn't eat well, almost nothing as compared with everyday..

There is unfortunately no swans nor birds specialist in the surroundings who can readily help me and this is why I am seeking your worthy advice to preserve my birds health.. Please help me...
