I prefer low humidity incubation, but humidity is really a case of finding what works for you, your methods, your eggs and your bators. I do know people who use the low humidity methods in the plastic bators such as the janoel and it's knock offs very successfully. The only time I don't recommend it is high altitude hatchers and cabinet bators. It's easy to tell if your humidity is working for your eggs by monitoring the air cells. Here's some more info if you are interested: http://letsraisechickens.weebly.com...anuals-understanding-and-controlling-humidity I have awesome results with this method. You can judge whether you need to higher or lower your humidity and not depend on someone else's "magic number".
