Mine each seemed to only have one miserable day and several days they felt a little punk. None of them died.
I don't know if it helped but I put some raw honey in their water.
Don't disturb the scabs, since it can spread the disease. You can paint some iodine on them to help dry them out. If the one is bleeding, you could separate her for a day or two, and try to make sure that she is eating and drinking well. Look inside her throat with a light since wet pox can cause yellow lesions inside the throat, trachea, and esophagus, and is more dangerous.
For respiratory diseases, Tylan 50 injectable is good for oral or injectable use in breast the muscle, or if the chicken is drinking well enough, you can use oxytetracycline, Gallimycin, or Tylan Soluble Powder in the water. Dosage if Tylan 50 injectable is 1 ml for a 5 lb chicken once or twice a day for 5 days by mouth, or 3 days if giving shots. Since many respiratory diseases are viral, antibiotics may not help, but if there is swollen eyes and thick nasal drainage, antibiotics would help.

I assume that you intend on cooking your eggs. If that is the case then they will be safe. Your eggs will properly be OK anyway because the Pox in chickens is different from chicken pox in humans. oxytetracycline, Gallimycin, or Tylan are useless for treating pox because it is a viral disease and at best antibiotics will only work on bacteria, although Tylan etc. may prevent opportunistic bacterial infections in a weakened bird.
Yes, that looks to be dry pox, more easy to see on the earlobes. Put some iodine on the scabs to dry them out, and don't disturb the scabs. Watch for any pox scabs near the eyes, which can lead to an infection. Here is some reading:
