Legs Sores

[BK9954]

My hereford and black calf have spot of missing fur. I thought the black one had warts but the spot is pretty big. The herefords is pink and had flies on it. Does not look raw. It has me concerned.They are walking and eating fine. The other 2 in the pen are fine. Any advice?

My guess would the first picture has lice? and the second ring worm.
