How do her droppings look? You can insert a gloved, lubed finger 1-2 inches into her vent to see if you can feel an egg. If she's egg bound she won't be able to pass droppings. If she does poop, how it looks may be important. As a new layer she could be having difficulty with an egg. It would be good to know if you can feel anything. If she's having trouble passing an egg then a calcium citrate +D (Citracal or equivalent generic) once a day can help with contractions and help her pass it. If you think she is sick, then a bath is not a good idea, but if she's having trouble laying, then a warm soak can help them relax and pass the egg. It can be particularly difficult to pass if it's soft shelled or shaped oddly.
