In full agreement with TwoCrows post above.
The other thing is that if she has had a partial impaction for some time, causing that pendulous crop, this will mean that she has not been getting the nutrients she needs to produce eggs. Whilst you are feeling her abdomen you will also no doubt notice if she is in good condition or skin, bone and feathers, as most of mine that have had a crop impaction have been. Some get so skinny that their crop is heavier than the rest of their body and tips them forward all the time.
