What might be wrong?

[New2COchicks]

I have a 4 year old Brahma. Her comb has been paler than her sisters the past 2 weeks. I don't think she is laying eggs anymore. She is eating and drinking. I see her quickly shaking her head often. She is walking and running, but definitely a little weaker with a stumble here and there. Her butt was full of poop and I cleaned all that out. I feel her comb's color came back a little, but still not vibrant like sisters. Some of her feathers have fallen out , especially around her head, but not a ton like a molt. Any suggestions? I did put probiotics in her water today.

Have you ruled out Cocci, mites / lice, and worms?

No not really. I put that earth powder on it each day now. I cleaned out coop well this week. How would I rule out each one in your opinion? For cocci..what do I look for? For Mites/lice where do I look? For worms...How do I look?

Taking stool samples to the vet can check officially for cocci and worms. Unofficially, puffed up birds, bloody droppings, pale combs, lethargic. Worms, messy bums, weight loss. Mites and lice, they are tiny, so hard to see. But you may see clumps around the feather shafts around the vent, under the wings, you might see some move around on their skin. Depending on the type of mite, some you can wipe a paper towell under roost bars at night and you might see little blood streaks.

There are many threads on BYC with more detailed symptoms, if you can't find them let me know and I'll search for some links.
