- In life and on Offer-up, everything is always negotiable- Purchased this perch for my chickens and with the weather out here in LasVegas, it doesn’t get nearly cold enough for this perch to turn on. The thermal perch turns on when the temperature hits 32 and below. The built in temperature sensor controls when the perch turns on and warms the chickens feet. I tested the perch to make sure it worked by putting it in our deep freezer. It works and would make a great tool for chickens who live in a much colder climate. It just doesn’t get cold enough out here to use. Measurements: Length: 36” **All offers will be taken Into consideration, Message with any questions**
