I've done the same thing with a dog cage except after seeing Eggsmerelda's feet suffering I replaced the floor. The cage was raised a couple of inches from the ground and no bedding added. I shoved a branch through the holes to make a roost and provided food and water. After 3 days I let her out and she was broken from her broodiness. If it had been really hot I might have squirted some water on the g et ound UNDER the cage floor to keeo the area cool.
