Fowl Pox but getting worse??

[AGirlandHerBirds]

Our sweet Angel and PIA seem to both have Fowl Pox. I’ve quarantined them from the rest of the flock (that SEEM ok) Angel (hen laying down) can barely walk and has stopped eating. I served her some rickets formula yesterday and she ate it up. No eating this morning. She has a foot she won’t put any weight on and lays in her own poo. I think I’ve done everything we can. (Baths, ointment, electrolyte solution, Rickets formula (yogurt, oats, beef cat food, honey, shredded apple and cod liver oil).

So what’s next??

My gut instinct says that they are dealing with something in addition to fowl pox. Any possibility of Marek's ?
