the check marks are a note that the judge makes to himself.
when it is written "color" it means the judge questioned the color or it was not right for what he was looking for. other notes you may see are wing, toes,beak- it is just a reminder for the judge that is something is wrong with that...
I bought mine when they first came out. and was about $250 ( I had parrots at the time). now they are are $300 and up but you might be able to find a used one.
i have one of these, a chick "buddy". it shows the heart beat of a chick about 10+ days incubated.
