Chester has these weird scabs...

[Chester]

they're all over his back! when you scratch them it makes him lick himself. Anyone know what they are?

Skin problems can be caused by dozens of different things like skin infections, fleas, mites, allergies etc. Only a vet seeing chester would be able to tell you what those scabs are from. I wouldn't wait too long to get him in, if it's a skin infection those can spread and cause more problems and some are even contagious to people. Take Chester to your vet. Good luck
