For bullet number 1, editing to add temperatures for a fan forced incubator and a still air incubator would make the article better.
The images for the article are not in the gallery. I did not find them in your stored images either. Adding them to the article would make it better. If you need help, please let me know.

Not a bad idea, but not something I'm fully prepared to do. It's just that built most of this a year ago and would forget to list a number of the materials I'm sure.
