Duck not acting right not laying

[LadyBubbles]

I have a 1 yr old blue Swedish Cayuga mix. I went out of town and the day after I came back she was acting off. Did not lay and has not for at least 3 days. She will drink, eat blueberries and peas but not duck feed. She is staying away from her flock for the most part just standing around or laying down for long periods. I have soaked her twice today and will again but it stresses her out a lot it seems as she does not like to be handled. I gave poultry cell last night and today still just going for the blueberries. I don’t think I feel an egg? But she is not even going for grass or mud.
