For my 2nd incubator, I am using this box with foam lining I used many times before, although I don't hatch in it. I needed more room. The glass is not attached, I use it as a lid.
Great pictures of all the eggs with chicks inside. Keep posting them. We set our first hatch on 3/3 and if all goes well will they hatch nearly the same day as my ordered chicks.
Please keep posting this great pictures.
