I'd like to see a picture of your birds. And why do you need heat if they are in your house? My daughter was wanting to get a bird and allow it to fly around the house but we have a cat and dog, which would be difficult to keep them from catching the bird.
Awwww....she must be a really sweet hen. And most people don't realize that chickens do have personalities and they can learn. But it takes someone special to keep one in the house. 🥰
