A hatcher is a incubator set to the lock down humidity. You use an incubator to get eggs to lockdown and then move them to a tray in the hatcher. This way you can keep the incubator running and add new eggs as room permits without having to deal with hatched chicks, cleaning it out etc. Of course you can do it all in one cabinet. So we refer to all as incubators and differeniate those dedicated to only the last days of hatching as hatchers.
I have two inexpensive incubators- a hova with turner and an lg- I can put two or more sets of eggs in hova, remove those that shld be locked down into the lg with paper towel to catch mess. The lg makes me crazy as an incubator but once closed as a hatcher its fine.
