Both wounds appear to be healing well. You can spray them with Vetericyn or slather them with neosporin (without pain prevention drugs, original formula only) but honestly it will probably heal up fine without you doing anything but keeping your hen away from anyone who would pick at it, and away from flies. Do you think a predator got her? My initial thought is you have a rooster that has cut her up with his spurs while mating, but I need more info to see how likely this scenario is. She could also have gotten caught in something and got injured trying to escape.
The wound that's less of a straight cut looks rougher - if you want to try and remove the scab and clean it out some, you can, but you can also just leave it. It will heal up just fine on its own most likely. Chickens can be amazingly resilient in some ways. The edges of those wounds, particularly the cut area, look healthy. Now if they get swollen, red, inflamed, then it's time to consider a systemic antibiotic and possibly a trip to the vet. I've seen similar wounds heal in a month or so without much help from me.
