They may possibly have mycoplasma (MG,) a chronic respiratory of chickens and other poultry. It is contagious and can be spread through the egg or by direct contact. The eyes look like they have conjunctivitis, which is common with MG. Tylan, Tylosin, or oxytetracycline are antibiotics that may treat symptoms when they have an outbreak.
There are some scaly leg mites in some pictures. Those are treated with applying vaseline or oil to the legs and rubbing it in twice a week for several weeks until new scales grow in.
Alao I see some frostbitten toe tips, and on the wattles of one. Frostbite of the feet may show up in the first week or two by the skin becoming black and shriveled. You may see the toes eventually fall off in a month or so. Wattles or combs will become rounded off eventually, but mild cases may heal.
