Hey, @Ridgerunner I'm so glad you posted this so the OP could see outdoor brooding with both methods....the heat lamp and Mama Heating Pad! We sorta cross posted there - I need to learn to pay more attention to that "new post" thingy that pops up on the bottom of the screen!
I will be very happy to share that with you. I have an article I did last year that might answer most of your questions and if you have any more, please feel free to ask! My run is made of cattle panels attached to steel fenceposts pounded into the ground, and it has worked better than I ever...
I you can swing it, get power out there. You never know when you may need a dim light. Here in Northern Wyoming it gets dark pretty doggone early and I'm not always done with my chores when it does. During the hot days of summer, a fan is nice to be able to use to cool the chickens down a bit...
