I have 2 geese and 2 ganders, all 7 months old. They are French Toulouse. One goose has been acting strange for about 2 days now. She doesn't seem sick, just acting weird. She just stands or lays in the same spot all day. She is honking and being loud, but she is not roaming or swimming with the others. I keep baytril, metacam and smz on hand at all times because I also have 70 ducks. Any suggestions?
