Which Antibiotic Should I Try?

[ddboersma]

Hello! I have another thread on here for my 22 week old hen with a lame leg. Long story short if possible, we have been dealing with a limp that turned into a lame leg for probably 3 weeks or more now. The leg just drags behind her when she hops around, and mostly lays out straight to her side when laying down. I have been treating for vitamin deficiency for about 8 days in hoping that might help (B100 complex). I also started as of yesterday Vitamin E in yogurt via syringe throughout the day, as she won’t touch the yogurt on her own.
Her stools are also loose/diarrhea most of the time and greenish (or yellow after the B100 vitamin is given). I don’t feel she has improved or gotten worse. I can feel her keel bone pretty prominently, though, even though I would say she eats and drinks normally.
I’m fearing the worst that we might actually be dealing with Mareks, in which case my whole flock is impacted and I can’t even imagine what’s to come (there are no others showing symptoms as of right now).
We also treated for coccidiosis and tape worm in July.
My question is, if I wanted to try and treat with antibiotics as a last ditch effort (if not vitamin deficiency or Mareks), which antibiotic should I use with these symptoms?? I have been googling and not feeling led one way or another.
I will continue to treat with vitamins as well. She has been in her own section of the run so as not to get picked on, but I don’t know if I should have removed her all along.
(Pics are from her hanging out in the landscaping by my house this morning after giving her bum a bath. The run is sand, not mulch).
Thanks for your time!

I personally would not use an antibiotic for her symptoms. The lame leg with a curled under foot looks like curled toe paralysis, which is a sign of Mareks or nerve damage to the leg. There are 2 differ watys to diagnose Mareks: one with a neceoosy and testing by the state vet after death or euthanasia. The second is a blood test by a lab, such as RAL, where they send you the materials to collect a blood sample, and send it back in to them for a pcr test. You can trim the toenail short to get that.

You don’t need an antibiotic

You don’t need an antibiotic

Meaning you don’t think it would be helpful, given her symptoms?

Is there anything else I should blood test for in addition to Mareks, in your opinion?

Yes

Possibly Avian Leukosis Virus. Symptoms present similar to Mareks, necropsy looks quite similar too.
