Chronic coccidiosis?

[beevee]

Good morning! I have a flock of 5 hens & a roo (buff orpingtons) and I just can't seem to get them all feeling good at the same time

I got them @16w back in August. In September, they were fighting an upper respiratory thing and I did some supportive care until one hen, "Matilda," had a severely swollen face and I threw in the towel. Paid an online vet to triage and we treated with Tylosin -- all better!

Except Matilda can't seem to get to 100%.... I suspected she's not all buff orpington because her face & comb are different shapes than the others so when everyone else's combs got bright red after Tylosin, I was patient because she was still a little pale. She's pinking up now at 6 months (with weekly nutridrench) but she is never vigorously red
Her poops were watery (and her butt feathers are just sad little frozen strings) for weeks but now are more grainy/granular? I've never seen parasites in her poo. The other chickens seem to have normal poo except yesterday one of the other chickens had foamy yellow poo, but she's in great health otherwise. No one has ever had bloody poops. Everyone's appetite & water consumption are great.
Matilda's feathers aren't quite as pretty, a little frayed/ruffled and she weighs much less compared to the others
Matilda wanders off by herself to take naps during the day. She's the only one that doesn't sleep on the roost with the others (recently taken to sleeping on the floor of the coop)
She's stable, just never been in great health since I got her. She's the sweetest one (of course) so I would like to do what I can for her to turn this corner.

I can't tell if this is parasites or coccidiosis or clostridium or ?? I still have the powdered Tylosin and I have corid (never used) but I don't want to be irresponsible with treatments. I haven't separated her from the flock but could make that happen.

Tried to paint a picture that might shout a particular diagnosis -- let me know what you think and thanks in advance!
(Vets do not want to see chickens in my area so I, unfortunately, don't have a place to take her to be seen, otherwise I would. And the online vet is a $40 fee I'd rather put towards treatment)

At 6 months old most Orpingtons are not bright red in the combs and wattles. They tend to start laying around 7-8 months and will usually not turn bright red until then (I have had over 40 orpingtons). She needs probiotics. When you give antibiotics it kills all gut bacteria that means both the good and bad. When the good gut bacteria is killed off it causes digestive problems. If you do not repopulate the gut with good bacteria (probiotics) it can result in constant gut and crop issues. It’s very crucial to get the good bacteria up. The gut is central to all things in the body for both humans and animals. I use Probios (tractor supply has it) or bene-bac paste that I get from chewy. As for her behavior being alone and not roosting it sounds like she is at the bottom of the pecking order which is normal if she has been sick constantly. Healthy chickens will often try to push sick chickens out of the flock keeping them at the bottom.

Hi! Thanks for replying! I realize I failed to mention that the flock is laying at full steam -- something like 3-4/day. I got these pictures this morning so you can see the visual differences I'm referring to. I was told when I got them that they were 16w and "about to start laying" but they didn't lay until after they kicked the upper respiratory infection.

All great information. I will get them some probiotics

Consider using a different product.. while nutri drench is good for weak chicks and may work well if no digestion is taking place.. using Rooster Booster brand Poultry Booster or Poultry Cell will go a lot farther to help the immune system recover.

What are you feeding including treats?

We've been feeding an organic egg layer crumble. A handful of meal worms/soldier fly larvae once a day. A special treat like an egg scramble or oatmeal+berries every couple weeks.

I'll look into those products! Thanks!
