Chicken quarters don't work well in bowls. Some people close off the kitchen with babygates to keep the dogs confined in there. Some will put down plastic table cloths or towels and teach the dogs to eat on them. Some people feed their dogs in crates. Some feed outside.
Many dogs will lick their eating area clean after they eat so no need to mop if your dogs do this.
Are you feeding a whole chicken quarter to each dog? What size are your dogs? Something you said made me think you were feeding pieces.
EDITED: I just looked at the pics of your dogs and I see they are petty small. Too small to eat a whole chicken quarter. I suggest you feed wings, drumsticks, thighs, or bone in breasts. It will be much easier that way. Much less messy and less work on you. I can't tell how large Isis is.
