Extreme heat issues

She was a unique bird, I got her as a hatchery choice bird and she had 5 toes on each foot but was as big as a bielefelder. Also, one of my first chickens. I wish it wasn't her, but am now learning the hard way.

Yup, I do that aswell how long can i keep them in there for?

I am just going to place it out in the run for them to stand in (and drink from) when they want.
