I definitely won't rearrange anything. I usually put the food bowl down wherever he happens to be, but I can start putting it in a specific place so he knows where it is.Good decision to keep him alone. You could be in a room with her where they could interact through wire, but Chili in the same space would probably stress him out. Just keep all of his stuff in the same place, and it should help him with food and water. I've had a couple of blind hens that did just fine that way.
I've also gotten rid of some toys he doesn't play with to reduce the clutter on the floor.
