I don't know the first thing about quail pens, brooders, or incubators. I am looking for information or suggestions on where to get good plans for home built pens and incubators. I have a friend on disability and he cannot afford new. I would like to surprise hime with one of each. What makes a good pen? I have seen many pics, but still have questions. What makes a good incubator? Any and all help will be most appreciated. Thank you.
