Young pekin duck is constipated-she's too young to lay

[10PekinDucks]

I need suggestions. One of my younger female pekin ducks has become constipated. I noticed last week that she was getting larger in the stomach but didn't pay attention to see if she was pooping until the other day. I've started soaking her in epsom salt water twice a day for the last 2 days. I'm afraid she's stopped eating. I gave her Poultry Cell yesterday and soaked some meal worms in epsom salt, I gave her some diluted plain greek yogurt today. I saw her poop almost clear this morning, and she pooped very small amounts in the water yesterday and today, but she seems to need something more. Any suggestions? I do NOT want to take her to the vet. I just had a duck at the vet last month for a bumble foot we didn't catch in time. Now we look at the ducks feet at least once per week and spray as needed.

-How old is she?
-Do you have a picture of the bump?
-When you say that you don't think she is eating or pooping much are you with her all of the time or do you mean just when you are around?
