Cocci?—first experience

[Hilltop Flock]

Hi, I have 2 chicks that are about 4 weeks. They are currently spending the day in a dog crate in my chickens’ run and going inside at night. This morning I noticed bloody poop. (This pic of was taken a couple of hours after the initial discovery.)

I saw that one in particular, was standing with her head tucked in, her feathers fluffed and slowly opening and shutting her eyes. I’ve begun treating with corid, both of the little ones. One seems completely fine, and the other is lethargic.

My question is this: should I teat all of my other chickens? None are showing signs of illness. They range from 10 weeks-1 year. They are not sharing food or water.

Treat both chicks that are together.

Liquid Corid dose is 2 tsp or Powdered Corid dose is 1 1/2 tsp per gallon of water. Give for 5-7 days as the only source of drinking water. Don't add anything else to the water besides Corid.
