poorly duck, thin & weak

[Blue]

this is Daffy ..... she has, as you can see, a twisted beak, like a smile. she has always been a loner but never struggled with the beak.

however, she is now looking really thin and has got quite muddy and is reluctant to swim.
we "dipped" her to get the mud off and clean her beak, her feathers seem oily enough.
she retreats to the house & is wanting to stay lying in the corner.

any suggestions as to what I could tempt her to eat?
they have pellets, corn & mixed flakes, and grass,hay & greens.
Ive threatened her with antibiotics.... they were wormed before Christmas.

I think she may need a trip to the vets- she may not be able to get enough to eat with her bill the way it is or it could be something more sinister underlying. Hope she is better soon.
regards, David
