Thank u too campingWhat calcium have you given her?
The best way to feel for an egg is to press your finger into the vent. Wear gloves and use lubricant. You can soak her in warm water with Epsom salt, first. @casportpony has a very good thread about egg binding.
I wouldn't rule out the coccidiosis. I've had many chickens get it and none of them ever had the bloody stools. It's just an overload of "bad" protozoa in the gut, and is treated with corid in the water. If she's not drinking on her own, you may have to use a syringe.
