One of my female ducks has been acting odd lately. She kinda hangs out by her self instead of with the other girl muscovy ducks and doesn't move much. She has been sitting all puffed up and sleeping way more than usual. All the other ducks have been acting normal lately. Some background: I had four ducks before who were all mallard derived then I purchased three muscovy ducks (two female and one male) The male died recently from a dog attack and while the two muscovy girls were shaken up at first they quickly integrated with the mallard derived ones. Could it just be from stress? She is a very very shy and quiet duck to begin with so could the loss of the male muscovy make her depressed? Any help is appreciated! God bless!
