We have bantams and recently put pinless peepers on our roosters tonight we checked on them and noticed this crust on them and one has a knot on his waddles and some have black dots on their combs and one has a curl to her comb? We removed the peepers but I don’t know how to treat them. We have a coop that has a large run but it has rained here for this last month.I am not sure if it is sickness or problems with the peepers or environmental? Thank you
Hi
@Adelia 
Welcome To BYC
Can you post some photos of your housing? How much space do you have?
How many chickens do you have?
You mention that they have a run, but it's been raining. Have they been staying inside the coop?
Good questions by the previous posters, if you can answer those, it would be much appreciated.
Did the roosters have mucous before you put on the pinless peepers?
Have you noticed any coughing/sneezing or watery eyes?
I do see blood in the nostril too - that could be from injury from the peepers. It would be good to clean the nostrils and look inside the beak to make sure there is no mucous, plaques or lesions. You can use a warm saline soaked compress to help loosen the mucous, gently remove as much as you can. You may have to do this a few times a day for several days.
The black dots on the combs look like they are from pecking. The curl of the hen's comb, I think that's just the way she is - some combs have a curve/curl or they flop over.
The eyes on the rooster. How long have they been like that? It would be good if
@Eggcessive chimes in on this with her thoughts. It's hard to know if that is an eye defect or is caused by disease like Marek's.
