I bought one of those things for my son's room to check on the Humidity since he has allergies and then bought a second unit that I put in the chicken coop. Now at one glance at the main unit in my kitchen I can check how warm it is in the chicken coop and also see the humidity. Soooooo cool !!! I think it will be a great help during the winter, since our coop is not insulated and I really want to see how good it will keep warm. The thing was only 25 Dollars so I think it is worth it to give it a try. So much fun to keep "track" on the ladies
