CRD? Snotty noses

[SeaPolka]

I have three pens next to each other, there's a trio in one, a trio in another and a bunch of Pekins in the last. My Ayam Cemani pullets recently started sneezing so I looked at them and have seen snot in their nostrils and one has a few bubbles on her eyes. None of the other chickens are like this but their cockerel is now also sneezing, ever since I paired them all up. I paid a lot of money for these (I'm in the UK) and the breeder said if there's any problems to ring him as a guy who bought some had his die. They have ruffled feathers but they've been wormed and treated regularly for mites and lice. They're free to graze, dust bathe, shelter from the rain, sleep in a cosy hutch. They always have ACV in their water. I think it could be a respiratory issue but I'm no expert, is this recoverable? They're for nothing other than my enjoyment but all the chickens in these pens have been paid for by myself (student) and people ain't cheap here.
This is the worse looking one

And this is from last week, it's their run thing which I'm currently rebuilding so don't mind the mess. There's now shelter over the back half and bird netting on top

Their hutch has adequate ventilation holes I made all along the back, so I don't think it's their sleeping conditions. But I'm completely lost. I don't want to lose them.

Mites and lice would not cause respiratory distress. Something like Mycoplasma, though, might. You might want to check with the guy who sold them to you to see if anyone has had any of his chickens checked for that (it requires a necropsy--someone would lose a chicken). I just went through it with my flock. It started with some new hens I bought from a reputable breeder, then slowly spread through most of my flock. I finally had one tested, and when it came back positive for mycoplasma, I put them all on antibiotics. I had already treated them for coccidia, worms, lice, and everything else possible. Poor things. Now, some 8-9 weeks later, we're clear of disease. But I still have to wait 2-3 more weeks before I eat their eggs again, after all those meds. The antibiotics I put my girls on was costly and required a vet's prescription. I think most of my adult hens would have made it without the meds, but I didn't want to risk it. The hen I sent off to be tested was close to dying, and some of my chicks died from it later. It also makes sense to put them on vitamins and feed them healthy snacks. I think all that helped my flock.

Sorry about that. I do think mine could have MG too but I read that they're carriers of it for life even if it can be cured. I can't get in touch with the guy anymore but I'm seeing the vet today, I would like bloodwork done on all of them and if they're all positive I will most likely cull the flock, if it's just the AC I will ask about preventative medication for the rest. It seems the AC brought it in and I've spent so much money on just buying all these kinds of birds, but it's one of them things I guess. Good luck with your hens and thanks for the advice
