Is this okay?

Never used a heat plate before. I’ve always used a heat lamp and raised chicks in my bedroom. They will be in a large glass tank in a shed with my pig. They are up on a shelf that’s too high for her to reach and the cord is going to a plug in the ceiling. The babies area is also fenced off. The pig is only here at night. I just have no idea how heat plates work and i want to hear from the people here if this is fine and if i need to use a different bedding.
