What is this?

Brand new to raising chickens I have 3 2 RIR and and autrolorp. One of my RIR has these blad spots and they are super red. I went to feed them this morning and I noticed a black spot on her back, I think its a scab. none of the other have it. I dont see any bugs on them. Help

Pictures would help to identify what is going on!

Just because you can't see any bugs, doesn't mean they don't have them. Sure wouldn't hurt to dust her with poultry dust.
