First of please only post one...(you posted this Three (3) times )
if her poop is watery she may be drinking a lot due to the hotter weather.
The crop...she might be getting "sour crop" with impacted crop or sour crop : Chickens may exhibit a large bulge in the crop area, diminishing weight, isolating themselves from the flock, hunching down or protecting their injury. The bird may also jerk their neck around trying to dislodge the blockage. Additionally, the stuck items in the crop may begin to rot, resulting in a sour smell coming from the chickens beak.
Carefully open the chickens beak and have a sniff to see if there is a sour smell. Although the odor is difficult to describe and may vary depending on what the bird has ingested, it should be obvious that there is an unusual and unpleasant smell coming from the chickens beak.
If you suspect the chicken may have a blocked or impacted crop, it is best to isolate the chicken and only provide water or organic vegetable broth (I have used kale and broccoli broth) to confirm that the hen is not able to pass waste.
-------------------------------
If she does not have any of the symptoms, I would wait until the morning BEFORE the chicken eats, an check to see if the crop has gown down or gone....It is normal for them to be extended if they have just ate or are storing it for the sleep hours
Best Wishes,
