Chickens suddenly lethargic and dying

[Eggcessive]

Corid will not harm them in any way, so I would start some. Most feed stores have it in liquid or powder form.

Didn’t have my phone on me just now when I went out but I saw several patches of mucousy, stringy stool.
Also one of the birds had a bulge on her chest. I’m guessing it’s the crop, it was boggy when I picked her up but I didn’t notice anything else. I have never seen it bulge that much in the past and my astute daughter pointed it out as well.

Can you get some photos of the poop?

The one that has a boggy feeling crop, feel of that first thing in the morning before she eats/drinks to see if it's empty. If it's not empty, then begin crop treatment. The following articles will help you determine what type of crop issue she may have (sour, impacted, slow, etc.). I would also look inside her beak for any sores, yellow patches or canker.
A lot of times crop issues are symptom of an underlying condition - some common causes are worms, coccidiosis and reproductive issues. I hope you can figure out what's going on. If you happen to lose another one, getting a necropsy will give you some answers.

Just bought some Corid and about to add to a five gallon water bucket. Should I change it every day or will the medicine last as long as the water lasts?

Here’s a pic of still I found this am.

If possible, make a fresh batch every day. Dosage for Corid is 1 1/2 teaspoons Corid powder or2 teaspoons of 9.6% Corid liquid per gallon of water.
Give for 5-7 days - make sure this is the ONLY water available during that time period. Mix a fresh batch at least once a day.

Thanks, I’ll replace the water daily for five days and retreat. Thanks!
