The egg quadrants simply clip together to allow eggs of one size to be incubated or eggs of different sizes to be incubated together when using different species specific quadrants.
Protected by Biomaster antimicrobial additive: proven to reduce bacterial growth by up to 99.99% and 100% safe for eggs, chicks and humans. Protects the incubator from microbial growth by reducing the risk of cross contamination and provides a more hygienic environment for your eggs.
I spoke to someone about 3 weeks ago about my incubator not working properly, and discovered I'd put my fan on the wrong way around after cleaning! I'd just like to say thank you so much for your help...
