I had a friend give me a bater. It was an older one made from galvanized metal. No insulation at all. Out of 51 eggs, I had only 2 hatch. At that moment I realized that the only viable part of that bater was the heating element and thermostat so I put those in the cabinet bater that i built. That alone save me several dollars. I decided to build my own because 2 of 51 was very updetting and I knew i could do better than that.Good for u gladd! That is awesome, I have a small Brower incubator right now- 13 eggs set!
