If they're still alive and still not drinking, put a bowl or pan of water in the coop immediately. Also, a small amount of food. Change is very stressful for chickens. They are also usually afraid of new things, like objects or different looking food. The important thing is to keep them alive right now. They can learn to use the nipples for the water later. They can learn to enjoy the run later.
I hope they're doing okay.
