Someone (more than one someone?) in my flock is having red, bloody poops. At first it looked like a solid red poop that was similar in color/texture to red velvet cake. But now it looks much more like a wet bloody poop. My chicks are 4 weeks old.
I'm confused about a few things. First, my chicks (from Murray McMurray) were all vaccinated for coccidiosis, which seems like the most likely culprit from what I see online. Second, I cannot identify anyone in the flock who appears sick. This has been going on for about 5-6 days, and everyone is active, eating, drinking, etc. This morning, one gal was off to herself and didn't come out when I opened the brooder (the rest all rush to the screen door and look outside and have fun pecking the wood floor). However, I picked her up, and she is clear-eyed, not too hot, and her vent is perfectly clean. She's a very light colored chick, so I would assume that there'd be at least a trace of red on her feathers if she was the one. She is not gaping or cranking her head back. I don't see anyone else with any traces either though, so whoever it is is hiding it well.
Any thoughts or advice? This is my first flock, and I've read everything I can, but I still feel like I'm so clueless!!

Here's the photo of the only girl who was off to herself this morning:


As a complete side note- I had ordered 15 "Easter Eggers", and two of the chicks were very light; this one, and another one that is almost perfectly white. Is this a normal color variation for EE's? Or did we get two ringers? We don't care, we love them all, and it's nice to have two that we can easily tell apart. Just curious.
