If it's hard then she may have eaten something that is stuck in the crop and won't pass.
If it's mushy it could be sour crop or slow crop. Both can be crop problems or caused by something lower in the digestive tract slowing or stopping things. See what you find before worrying to much about what may or may not be. As for the worming, the recommended withdrawl period for eggs for most common wormers is 14 days after dose, so most commonly, they are dosed twice, 10 days apart so total withdrawl from eggs would be 24 days. Most of the time worms will not be visible in the droppings, the eggs are microscopic. If you have a vet that will do a fecal float test for you that will rule that in or out for you and save you from treating needlessly if that's not an issue and if it is you can use the best medication for whatever parasite is identified. Just as added info if you do decide to or need to worm at some point, I would not use wazine as a first time wormer, especially if you don't know for sure if/what worms are there. Wazine only kills round worms and it kills all at once. If a bird is carrying a heavy load of worms there is an increased risk of overwhelming the bird or causing a blockage. Just my 2 cents on that, hope it's not too much info at this point.
Here is a very good article on crop problems in the event that it seems to be going that route, it's just one possibility to rule in or out:
