Cocci? Blood in poop. Ruffled feathers

[KAswan]

Hello. I’ve read some of the other posts about this but not sure if this is cocci. I found blood in the poop as you can see in photo, one morning. I’ve administered the medicine orally. I’ve not seen blood in the poo again. The birds feathers are getting all separated which I saw somewhere else may also be a symptom. They are eating, drinking, active, not droopy. I haven’t figured out which chicken it is but one chicken has more separated feathers than the others. The others feathers are starting to separate now a couple days later. I only administer the medicine for three days, so today is the last day. Then I’ll add it to the drinking water. Any recommendations? Do you think this is cocci? The hens are 3 years old. I’ve gotten mixed messages from other forums.
Thank you!!

Feathers are getting more scoured and separated. I don’t know what to do. Does anyone know if I shouldn’t keep giving her the cocci meds? I got ratios from a thread here which said 1-3 days, 1-2 times a day. I’ve given them 4 doses over the last 3 days. No more blood in poop. 1 is looking more sick, the feathers I mentioned and sitting low. Still eating a lot and drinking.

Thank you to anyone who can help me? I’m so grateful for help in the past. I’m so worried and I don’t even know what it is. No more blood in poop.

It's not common for 3 year old birds having coccidiosis. Closely inspect your birds for lice/mites (especially mites.) I recommend that you worm your birds with Safeguard liquid goat wormer or Albendazole.
