I would definitely get a water heated, just like a dog bowl heater from Amazon, put a strip of chicken wire in front of it so that they can only get their heads in there, and then you'll only be filling it a few times a week depending on how many quail you get. How many are you planning on getting?
I am getting into quail as well is this is a wonderful question! Are you raising quail for meat or eggs? Or both lol. I as well live in Michigan, more in the Ludington, GR, area, where are you?
