Holds over 600 eggs. Works great, keeps humidity and temp very well. This unit comes with a fan, I was given an extra when I bought it so you can have that also. It comes with 6 trays and a tray on the bottom for water. It is already sent for a temp of 100. It only takes a day to warm up. I have hatched over 100 eggs from this bator at one time. And thats only because I didnt have any more eggs to put in it. I don't know the name of it or how old it is, sorry. I just know it works really well. This can only be a pick up and I can have it running if I know your coming.
