I'm using the setup that I've been using for the previous batches. It's a cookie cooling rack bent into a V shape. On top is a heating pad. And the entire thing is covered in felt. They keep squishing it flat somehow!
Oh ok! I've seen those before! I actually intended to make one but I couldn't find a heating pad that didn't have an automatic shut off. The heat plates were definitely more expensive but it has been worth it! I hope your chicks figure it out soon! I'm sure that's why they've been making more of a ruckus for you.
