If she was wormed that recently with Valbazen then I would not suspect a big enough worm load to be causing her this kind of trouble. If her lower abdomen is swollen I'd suspect she may be laying internally. Or she may be developing ascites in relation to some other problem.
I had a hen last spring who developed ascites and never did recover, vet did a necropsy and found a heart defect. I have another hen right now who has stopped laying and is becoming swollen just in the lower abdomen area, suspect internal laying with that one, we'll see tomorrow when she goes to the vet.
