I have 9 geese that are about 2 months old. They are on starter feed and eat grass from the yard. Yesterday I notice that one was laying down and breathing funny. After making the goose drink, it acted fine and then this morning it started doing the same thing. The goose can stand and walk but is shaking and still breathing funny and I have not seen it poop recently...... All other eight geese are fine....... PLEASE HELP.
