Do a search for sour crop, impacted crop and pendulous crop up in the window on the upper left side of this webpage. There are quite a few threads about this. My rooster was having issues for awhile, but he recovered nicely. His crop was big and hard at first, so I switched him to soft foods - wet mash, applesauce, egg yolk- and massaged it with a downward motion several times per day. I put apple cider vinegar in his water. He was better in a couple of days, but relapsed... I think he was eating really tough, fibrous grass and clogging it up again. I did the treatment for another week and he has been fine ever since.
The crop is basically a holding tank, so it will be large if they eat and drink a lot. Check her first thing in the morning, and if it is still large then you should begin treatment. Good luck! I'm sure they will both be fine, especially since they are acting normal.
