Yep its a hatcher and yes you can incubat in it as well. The big trays are are for those big birds with skiny leggs. I belive that you can still use thelm to hatch chicks in. The good news is you got a great buy The really great news is that if you get realy into hatching chicks and you run across a reg bator or 2 or 3 or 4 or...... you have a hatcher
more eggs at a time
and i also belive that you can even get reg size hatching trays for chicks later on if you need to. The clear door will make hatching fun.
