Right, wrong, or indifferent, I would worm if you need to, and my concoction right now is Tylan 1 tsp per gallon mixed with a tsp of sulfadimethoxine in that same gallon for 7 days. If your chicken is immunosuppressed due to Marek's, or suffering from bacteria or cocci, this may work. Marek's does suppress the immune system and this will cover the opportunistic bugs.
I don't have any Tylan, is it a multi-wormer? I do have Wazine.
I put the bird on some doxycycline, not sure about the dosage though (have some 100 mg tabs left over from one of my dogs). This pullet does NOT look good, she is standing but very lethargic, wing tips actually touching the ground.
No signs of respiratory or sinus problems. I didn't even think about cocci, we have had rain the last 3 days. I looked at the poop where she slept and no signs of blood.
Tylan is a good med for respiratory bacteria, but also good for other things:
Chickens: For the control of mortality caused by necrotic enteritis (NE) associated with Clostridium perfringens in broiler chickens. As an in the treatment of chronic respiratory disease (CRD) associated with Mycoplasma gallisepticum in broiler and replacement chickens. For the control of CRD associated with Mycoplasma gallisepticum at the time of vaccination or other stress in chickens. For the control of CRD associated with Mycoplasma synoviae in broiler chickens.
Tylan is in the same family as Erythromicin. My concern is about Clostridium, Cocci, and E. Coli. Tylan and sulfadimethoxine would cover treat them. I use these because I have NO experience with using other meds for what I want. There are other meds to use. From 3 necropsies, I have had 3 chickens die from worms, enteritis, cocci and e. coli. One from Aspergillosis (fungus). Those can be opportunistic bacteria that can takeover a chicken if they are immunosuppressed which is something that Marek's exposure can do. I just sent another chicken for a necropsy. She died at one year old and I don't know why.
Wazine is only for roundworms, not the other worms.
